PROBLEM TO BE SOLVED: To manufacture a coil element at low cost without applying high pressure to a coil. SOLUTION: A coil 2 is housed in a molding die 5, the molding die 5 is filled with a magnetic powder 7 containing a binder resin, and then an inductive magnetic field 8 is applied to the magnetic powder to allow it to generate heat so that the binder resin is heated and molded to make the coil element. The molding die 5 is made of non-metal such as polytetrafluoroethylene resin or the like, for example. COPYRIGHT: (C)2006,JPO&NCIPI
