<p>PURPOSE:To eliminate insufficient insulation between a planar fusion coil and a ferromagnetic material by providing a molded item having constant thickness around the fusion coil and sandwiching the fusion coil between ferromagnetic materials thereby suppressing the fluctuation in inductance. CONSTITUTION:A molded item 1 having constant thickness is provided around a fusion coil 2 which is then sandwiched by ferromagnetic plates 3. The molded item 1 is provided with a channel 1b which leads out the fusion coil 2 set in the hole part 1a. The molded item 1 is produced by injection or casting a thermoplastic resin or a thermosetting resin or punching a plate. Alternatively, the molded item 1 is made of a soft magnetic oxide material, an amorphous alloy, or a soft magnetic metal material having super fine texture of crystallized amorphous alloy.</p> |
