ABSTRACT:
A capacitor has electrodes at surfaces thereof, with one of the electrodes secured onto one surface of a grounding metal. Through conductors pass through the capacitor and the grounding metal and are connected to the other electrodes so as to achieve electrical continuity. An insulating case is provided at one surface of the grounding metal, with one end of the insulating case fitted around the external circumference of the raised portion of the grounding metal. Insulating resin fills a space inside the insulating case, the internal space of the grounding metal and a space around the capacitor. The insulating resin comprises an epoxy resin containing a brominated fire retardant, and the brominated fire retardant is a brominated aromatic glycidyl ether.
