Abstract: An electronic component manufacturing apparatus has a holding member for holding an electronic component body, a surface plate, a moving unit that causes the holding member and the surface plate to relatively move, and a control unit that controls the moving unit. The control unit causes the moving unit to simultaneously perform a distance changing movement for changing, by shortening or extending, the distance between an end face of each electronic component body and a surface of the surface plate, and a position changing movement for changing a two-dimensional position where the end face of the electronic component body is projected on the surface of the surface plate in such a manner that the direction in which the two-dimensional position moves in parallel with the surface of the surface plate successively varies (for example, along a circular path).
Abstract: In a coil component, a shield layer is provided after the unevenness of the surface of an element body is smoothened by the surface being covered with an insulating layer. A Cu layer of the shield layer is provided on a smooth surface, and thus a thickness variation can be suppressed and the Cu layer can be formed with a substantially uniform thickness. In the coil component, a point where the shield layer is thin or a point lacking the shield layer is unlikely to be generated and a functional degradation of the shield layer is effectively suppressed.

Abstract: A coil component in which a change in thicknesses of the winding part is prevented is provided. According to the coil component, since each of a pair of neighboring resin walls and a seed part between the pair of resin walls are separated by a predetermined distance, a plating part grown on the seed part is easy to grow uniformly between the pair of neighboring resin walls. For this reason, the winding part whose surface is gentle and in which a change in thickness is prevented is obtained by plating growth.
