Abstract: A high voltage capacitor comprises a columnar capacitor element body, made of a dielectric material, having a pair of principal surfaces opposing each other; a pair of electrodes arranged on the respective principal surfaces; a pair of terminal metal fittings connected to the respective electrodes; a case; and a resin part. The case contains a resin material and has a bottom part formed with an opening for exposing the terminal metal fitting and a trunk part extending from an edge of the bottom part in a direction intersecting the bottom part. The bottom part and trunk part define a space for containing the capacitor element body. The resin part is made of an insulating material and arranged within the case so as to seal the capacitor element body within the case. The case has a degree of hardness lower than that of the resin part.
