Abstract:
A high-voltage capacitor comprising:at least one grounding member having a raised portion provided with at least one through hole; at least one capacitor element including a dielectric ceramic member having at least one through hole and is provided with electrodes at surfaces where said through hole of said dielectric ceramic member opens, one of said electrodes being connected to said grounding member so as to achieve electrical continuity; at least one through conductor passing through said grounding member and said capacitor element and connected to another of said electrodes so as to achieve electrical continuity; at least one insulating tube covering said through conductor; at least one insulating case provided at one surface of said grounding member; at least one insulating cover provided at another surface of said grounding member opposite said one surface; and insulating resin filling a space inside said at least one insulating case, a space inside said at least one insulating cover and a space around said at least one capacitor element, wherein: said at least one insulating case comprises a mixture containing polybutylene terephthalate and an inorganic substance containing glass powder and ceramic powder, the content of said inorganic substance is set within a range of 15 wt % to 45 wt % relative to the quantity of said mixture.
