PURPOSE:To stabilize quality, and to contrive to enhance productivity of a high- frequency coil by a method wherein a holding part to hold a drum type core is provided integrated in one body to the terminal block of the high-frequency coil. CONSTITUTION:Drum type core holding pieces 17, 18 of two pieces to cover the peripheral side and the top surface of the under edge flange 14 of a drum type core 13, the peripheral side of the winding core part 15 of the drum type core 13, and about 1/4 of the under surface of the top edge flange 16 of the drum type core 13 are provided as to face mutually to the top surface of a terminal block 11. The drum type core 13 is inserted to be fixed from the side utilizing elasticity of the drum type core holding pieces 17, 18 between the drum type core holding pieces 17, 18 thereof. The part to be arranged with the drum type core holding pieces 17, 18 on the peripheral side of the winding core part 15 is provided to a part of the inside periphery of a coil 19. Accordingly, because assembly operation can be performed simply and moreover correctly, quality can be stabilized and enhancement of productivity can be attained. |
