    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.

    Abstract: In a planar coil element, the quantitative ratio of inclined particles to total particles of a first metal magnetic powder contained in a metal magnetic powder-containing resin provided in a through hole of a coil unit is higher than the quantitative ratio of inclined particles to total particles of the first metal magnetic powder contained in the metal magnetic powder-containing resin provided in other than the through hole, and many of particles of the first metal magnetic powder in the magnetic core are inclined particles whose major axes are inclined with respect to the thickness direction and the planar direction of a substrate. Therefore, the planar coil element has improved strength as compared to a planar coil element shown in FIG. 9A and has improved magnetic permeability as compared to a planar coil element shown in FIG. 9B.

    Abstract: In the coil component, the edge of the aperture of the protection film covering the coil from the lower surface side of the element body does not extend in the same plane. In this case, even if a crack occurs in the joint region between the coil and the bump electrode, the crack is less likely to cross the joint region as compared with the case where the edge extends in the same plane. Therefore, in the coil component, the crack is effectively suppressed.
