Through conductors pass through a capacitor and a grounding member. Insulating tubes cover the through conductors respectively. An insulating case is provided at one surface of the grounding member. An insulating cover is provided at an opposite surface of the grounding member. Insulating resins fill a space inside the insulating case, a space inside the insulating cover, and a space around the capacitor. The insulating case is constituted of a mixture containing polybutylene terephthalate and an inorganic substance which contains glass powder and ceramic powder. The content of the inorganic substance is set within a range of 15 wt % to 45 wt % relative to the entire quantity of the mixture.
