Abstract

An insulating sleeve 6 made of ceramic hermetically fixed into an opening in a terminal supporting plate 7 in a battery sheath made of metal, a positive terminal 4 made of an aluminum alloy or negative terminal 5 made of a copper alloy is inserted in the insulating sleeve, and a metallic ring is fitted over the positive terminal 4 or negative terminal 5. The inner edge of the metallic ring 11 and the positive terminal 4 or negative terminal 5 are hermetically fixed to each other by an aluminum-based brazing metal 8 or copper-based brazing metal 9, and the outer edge of the metallic ring 11 and the insulating sleeve 6 are hermetically fixed to each other by an aluminum-based brazing metal 8 or copper-based brazing metal 9.
