摘要： To provide a composite capacitor that withstands higher voltages and handles the high-frequency operations of switching elements. In a main capacitor 10 formed of a metallized film, first and second plate conductor terminals 12c, 13c as cathode and anode are continuously connected to first and second plate conductor bodies 12a, 13a. In a parallel plate sub-capacitor 20, a sheet dielectric 21 is inserted into a gap between opposed first and second electrode plate bodies 22a, 23a. First and second electrode plate terminals 22c, 23c are continuously connected to the first and second electrode plate bodies 22a, 23a. The main capacitor 10 and the sub-capacitor 20 are disposed in close proximity to each other. The first and second plate conductor terminals 12c, 13c and the first and second electrode plate terminals 22c, 23c can be connected to each other by the terminals of the same polarity.
