A high voltage capacitor used for a low-pass filter circuit or the like in a magnetron oscillator circuit of an electronic cooking range includes in combination, a capacitor unit, a ground terminal into which the unit is inserted, two perforating conductors inserted through two through-bores extending in the capacitor unit, insulating casings encircling the capacitor unit on both sides of the ground terminal, insulating resin disposed in both of the insulating casings and surrounding the capacitor unit, an electrode at the outer periphery of the capacitor unit, and electrodes at the inner periphery of each through-bore which surround and are conductively coupled to each perforating conductor. When compared to a conventional high voltage capacitor, the present invention has a reduced number of components, is simple in construction, and is not subject to a lowering of the breakdown voltage durability caused by a heat cycle or the like.
