    Abstract: PROBLEM TO BE SOLVED: To provide a planar coil element achieving intensity and magnetic permeability at the same time.SOLUTION: In a planar coil element 10, a coil part 19 has a magnetic core part 21 in which metal magnetic powder containing resin 20 includes a first metal magnetic powder 30. Proportion of tilting metal magnetic powder in the first metal magnetic powder 30 is greater in the core part 21 than outside of the core part 21, and in most of the first metal magnetic powder 30 in the core part 21, major axes thereof tilt against a thickness direction and a surface direction of a board 16. Therefore, intensity in the planar coil element 10 is increased comparing to one in a planar coil element 110 in Fig. 9 (a), and magnetic permeability in the planar coil element 10 is also increased comparing to one in a planar coil element 210 in Fig. 9 (b). Thus, the planar coil element is provided with achieving intensity and magnetic permeability on a high level at the same time.

    Abstract: PROBLEM TO BE SOLVED: To provide a planar coil element manufacture of which is facilitated by an easy-to-handle resin, and to provide a manufacturing method therefor.SOLUTION: In a planar coil element 10 and a manufacturing method therefor, a metal magnetic powder-containing resin 20 containing a flat or acicular first metal magnetic powder 30 further contains a second metal magnetic powder 32 having an average particle diameter (1 μm) smaller than that (32 μm) of the first metal magnetic powder 30, and thereby the viscosity of the metal magnetic powder-containing resin 20 decreases significantly. Consequently, the metal magnetic powder-containing resin 20 can be handled easily when it is applied and shaped to surround a coil 19, thus facilitating manufacture of the planar coil element 10.
