ABSTRACT:
A 3-terminal capacitor includes a wound unit which includes first and second longitudinal insulation sheets having substantially the same length which are laminated. First and second conductors are respectively formed on corresponding main surfaces of the first and second insulation sheets, so that one of the insulation sheets is sandwiched between the two conductors. The first conductor is longitudinally formed with substantially the same length as the first insulation sheet, and the second conductor is formed to be sufficiently shorter than the second insulation sheet. When the first and second insulation sheets are wound together with the first and second conductors to form the wound unit, two first terminals fixed on the first conductor at a predetermined interval and a second terminal fixed on the second conductor are exposed outside the wound unit.
