  • Patent number: 8717740
    Abstract: An electrolytic capacitor in which a capacitor element can be fixed firmly into a metal case without having adverse effects on the electrical characteristics of the electrolytic capacitor. An anode foil provided with an anode internal terminal and a cathode foil provided with a cathode internal terminal are wound or laminated through a separator to produce a capacitor element. The capacitor element is then contained in a metal case together with a driving electrolyte, and then the side surface of the metal case is caulked to press and fix the capacitor element, thus producing an electrolytic capacitor. The electrolytic capacitor is characterized in that a tape material is wound by a plurality of turns around the outer circumference of the capacitor element between the capacitor element and the caulking of the metal case such that a total thickness of the tape material is so large as to relax deformation of the capacitor element when the side surface of the metal case is caulked.
