Abstract

A sealed battery includes a case, an internal terminal, an external terminal, and an insulating holder. The internal terminal of the sealed battery includes a collector connected to an electrode body, a shaft part exposed outside the case, and a crimping part that is provided in an upper end portion of the shaft part. The crimping part is formed by pressurizing and deforming an upper end portion of the shaft part such that the crimping part extends along an upper surface of the external terminal. Then, the external terminal arranged outside the case is configured so that a linear expansion coefficient on a side of the upper surface and a linear expansion coefficient on a side of a bottom surface in contact with the insulating holder are different from each other.
