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. |
