A flowable insulating resinis placed in a sheet-like molding die space and conductive magnetic particlesare dispersed in the insulating resin. A first magnetic field Gis acted in the sheet thickness direction on the position where a conductive path is to be formed in the die space, and conductive magnetic particlesare locally collected together to form a conductive path. Simultaneously, a second magnetic field Gis acted in the sheet thickness direction on the intermediate region and the magnetic field Gis moved in the lateral direction to move conductive magnetic particlesleft in the intermediate region to join the collection forming the conductive path. As a result, the number of the conductive magnetic particles left in the insulating resin becomes smaller.
