Abstract

A battery includes current collectors for electrically connecting a power generating element contained inside of a battery case to external terminals, respectively. A caulking head of a rivet for fixing the negative current collector to a cover is contained in a engagement recess which is a space inside of a engagement receiving portion in the cover. The positive current collector is caulked to the cover via a shaft of the positive external terminal. A caulking head at a tip end of the shaft is contained in the engagement recess which is a space defined inside of the engagement receiving portion. The caulking heads do not project from a lower surface of the cover, and therefore, a clearance space defined between the power generating element and the cover is set to the minimum.
