摘要

An insulator (6) comprising a slit (9) is adhered on an outer peripheral portion of a collector core (4). A radiator (7) is adhered on the outer peripheral portion of the insulator and has a slit (10) in a portion corresponding to the insulator slit. The collector core is cut off at portion corresponding to the two slits.
