Abstract
A capacitor has a capacitor element, a packaging material, and a sealing material. The capacitor element has an anode foil coupled to an anode terminal, a cathode foil coupled to a cathode terminal, a separator, and an electrolyte layer. The anode foil, the cathode foil and the separator are rolled together. The separator is between the anode foil and the cathode foil. The electrolyte layer is formed between the anode foil and the cathode foil. The packaging material has an opening and packages the capacitor element. The sealing material has a through hole where the anode terminal and the cathode terminal pass through and seals the opening of the packaging material. A given space is provided between the sealing material and the capacitor element. A stopper for securing the space is provided on at least one of the anode terminal and the cathode terminal.
