Abstract: In an electric storage device, a terminal plate includes an element-connecting part electrically connected to a first electrode at a first end of an electric storage element, and an external terminal connected to this element-connecting part. A sealing member is on the element-connecting part, and includes a hole where the external terminal is inserted. The sealing member and the external terminal seal an opening of an outer jacket. The external terminal includes a tapered part on its outer periphery at a tip, and is partially exposed from the sealing member. The tapered part includes a first end and a second end farther away from the element-connecting part than the first end. An edge of a side wall at the opening of the outer jacket is between the first and second ends of the tapered part in a first direction extending from the bottom to the opening of the outer jacket.

Abstract: The capacitor has a capacitor element, a tubular metallic case, an electrolyte, and a terminal plate. The case contains the capacitor element and is joined to a first electrode of the capacitor element at its inner bottom surface. The terminal plate is joined to the second electrode of the capacitor element and seals the opening of the case. At least one of the terminal plate and the case is provided with a through hole, into which a hermetic plug made of a rubber-like elastic body and having an external diameter larger than a diameter of the through hole is inserted.

Abstract: A capacitor includes a metal case having an opening, a capacitor element accommodated in the metal case, an electrolyte accommodated in the metal case, and a sealing rubber sealing the opening of the metal case. The sealing rubber seals the opening of the metal case while the sealing rubber is compressed to have a stress applied thereto. The stress is not lower than 0.5 MPa and not higher than a predetermined maximum value. This capacitor prevents the electrolyte from leaking, thus having high reliability.
