Abstract: A magnetic element may include a first core member, a second core member facing the first core member along an entire outer periphery thereof, a coil, and a base shaped body on which the first core member and the second core member are placed. The base shaped body is provided with a base member and a terminal member, and the terminal member is provided with a binding terminal part, which projects outward in a first corner part of the base member and projects from the base member on a side lower than a portion of a winding frame part side of one flange part. The second core member is provided with a cutout part at a portion corresponding to the first corner part of the base member for allowing insertion of an end drawn out from the winding frame part in a state of not contacting the second core member.

Abstract: An antenna coil may include a first coil portion wound with coil wire; a second coil portion wound with coil wire and intersecting with the first coil portion; and a case having a coil receiving portion receiving the first coil portion and the second coil portion, in which the first coil portion and the second coil portion are disposed so that extending directions of the respective coil portions are directed in diagonals direction of the coil receiving portion.

Abstract: A problem to be solved is to prevent leakage of magnetic flux in a magnetic element. A magnetic element has a winding having conductivity, and a core member disposed in a state that the winding is wound, in which the core member includes a first core member having a bottom wall and a plurality of peripheral walls provided to stand on peripheral side portions of the bottom wall, and a second core member having a plate shape which is cross-shaped or substantially cross-shaped, in which cutout portions for allowing fitting of end portions of the cross shape of the second core member are formed in the peripheral walls of the first core member.

Abstract: A coil part used in a antenna coil has a cross shape core that includes: a first winding frame part extending a first direction and being provided with a coil, and a second winding frame part extending a direction crossing the first direction and being provided with a coil. A first core including the first winding frame part is interlocked with a second core 20b including the second winding frame part.

Abstract: The size of an antenna coil is reduced, and it is possible to prevent a lowering of the reception sensitivity due to a difference of the arrangement position of the antenna coil. On a winding frame of a ferrite core, a first coil and a second coil are wound in such a manner that their winding axes orthogonally intersect each other. A third coil is wound around an outer circumference of the first coil and the second coil in such a manner that the third coil's winding axis orthogonally intersects the winding axes of the first coil and the second coil.

Abstract: The invention provides a coil part used for an antenna coil that improves the production rate and enhances its sensitivity. A coil part used in a antenna coil has a cross shape core that includes: a first winding frame part extending a first direction and being provided with a coil, and a second winding frame part extending a direction crossing the first direction and being provided with a coil. A first core including the first winding frame part is interlocked with a second core including the second winding frame part.

Abstract: The present invention provides an antenna coil capable of attaining high sensitivity by increasing a core length, the number of turns of wound coil or a coil length without increasing the antenna coil size. An antenna coil 10 includes: a first coil portion 211 wound with coil wire 21A; a second coil portion 212 wound with coil wire 21A and intersecting with the first coil portion 211; and a case 30 having a coil receiving portion 34 receiving the first coil portion 211 and the second coil portion 212, in which the first coil portion 211 and the second coil portion 212 are disposed so that extending directions of the respective coil portions 211, 212 are directed in diagonals direction of the coil receiving portion 34.

Abstract: The size of an antenna coil is reduced and it is possible to prevent lowering of the reception sensitivity due to difference of the arrangement position of the antenna coil. On a winding frame (3) of a ferrite core (2), a first coil (5) and a second coil (6) are wound in such a manner that their winding axes orthogonally intersect each other, and a third coil (12) is wound around an outer circumference of the first coil (5) and the second coil (6), so that a winding axis is provided to be orthogonal to the winding axes of the first coil (5) and the second coil (6).
