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 a planar coil element and a method for producing the same, a metal magnetic powder-containing resin containing an oblate or needle-like first metal magnetic powder contains a second metal magnetic powder having an average particle size (1 μm) smaller than that (32 μm) of the first metal magnetic powder, which significantly reduces the viscosity of the metal magnetic powder-containing resin. Therefore, the metal magnetic powder-containing resin is easy to handle when applied to enclose a coil unit, which makes it easy to produce the planar coil element.
