Patent ID: 11728550

Abstract:
The present disclosure enables a decline in a joining force between an internal terminal and an external terminal to be suppressed even when a load is applied to a sealed battery from the outside. In a sealed battery disclosed herein, an external terminal includes a plate portion and a flange portion. The plate portion has a rectangular shape and includes an internal terminal joining portion that is joined to the internal terminal at one end of the plate portion in a lengthwise direction and an external device joining portion that is joined to an external device at another end of the plate portion in the lengthwise direction. The flange portion is arranged in at least one side edge portion of the plate portion in a transverse direction so as to rise approximately perpendicularly with respect to the plate portion. A first imaginary line which passes through a nearest point of the internal terminal joining portion to the external device joining portion and which is parallel to the transverse direction of the plate portion intersects with the flange portion.
