    摘要： 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.

    摘要： A coil component 1 includes a substrate 2, a planar spiral conductor 10a formed on a top surface 2t of the substrate 2, a lead conductor 11a connected to an outer peripheral end of the planar spiral conductor 10a, a dummy lead conductor 15a formed on the top surface of the substrate 2 and between an outermost turn of the planar spiral conductor 10a and an end 2X2 of the substrate 2 and free from an electrical connection with another conductor within the same plane, external electrodes 26a and 26b arranged in parallel with the top surface of the substrate 2, and a bump electrode 25a formed on a surface of the lead conductor 11a and connects the lead conductor 11a with the external electrode 26a. The external terminals 26a and 26b have a larger area than the bump electrodes 15a and 15b for securing a bonding strength.

    摘要： In a coil component, an uneven structure provided by an insulation layer and a resin wall contributes to extension of a contact area with respect to a magnetic body, so that an adhesive force with respect to the magnetic body is improved. In addition, the magnetic body protrudes downward toward an exposed region of the resin wall corresponding to a recessed portion in the uneven structure, a volume thereof is increased, and coil characteristics such as an inductance value are improved.

    摘要： An upper end portion and a lower end portion of a second magnetic portion of a coil component are further away from a coil than when a third part and a fifth part are not present. For this reason, a magnetic flux is unlikely to be concentrated in the upper end portion and the lower end portion of the second magnetic portion, so that magnetic saturation is unlikely to occur. Therefore, improvement of direct current superimposition characteristics is realized in the coil component.

    摘要： 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.
