Abstract: A coil component includes: a bar-like core; and a winding part formed of a conducting wire that is wound in a plurality of layers around the outer periphery of the core according to a solenoidal winding method. Winding collapse preventing shifts D1 to D4 each corresponding to a plurality of turns between an end part of a lower winding layer and an end part of an upper winding layer are respectively set to both end parts in the winding width direction of winding layers of the winding part. In transitioning from the lower winding layer to the upper winding layer, the conducting wire is turned back from the end part of the lower winding layer, and is obliquely wound in a small number of turns across each winding collapse preventing shift corresponding to the plurality of turns, and dense winding of the upper winding layer is started.

Abstract: A coil component including: a magnetic core which is formed by a magnetic material and which has a top surface, a bottom surface facing the top surface and a side surface continuous approximately perpendicularly to the top surface and the bottom surface; a coil which is buried inside the magnetic core and whose end portion protrudes from the side surface of the magnetic core; a flat-shaped terminal which protrudes from the side surface of the magnetic core, is bent toward the bottom surface of the magnetic core and is connected with the end portion of the coil, wherein there is formed an opening portion at a position corresponding to the place which is bent for the flat-shaped terminal from the side surface to the bottom surface of the magnetic core.

Abstract: Provided is a magnetic component capable of omitting a process of binding both ends of a lead wire to terminals and having stable connection between the lead wire and the terminals. The magnetic component is provided with a core (2) including a spool portion around which a lead wire (3) is wound, and external terminals (4, 5) to which the both ends of the lead wire (3) are connected. Each of the external terminals (4, 5) includes a protruding portion (terminal end fixing portion) which is capable of receiving movement of the lead wire (3) in a direction opposite to a winding direction, and the external terminals (4, 5) and the lead wire (3) are connected to each other.
