ABSTRACT:
A nonaqueous electrolytic secondary battery has a seal whose transparency and permeability with respect to external gas or moisture can be suppressed to a low level and which has high reliability. The nonaqueous electrolytic secondary battery has an electrolytic solution injection port (32) for injecting a nonaqueous electrolytic solution and an expansion plug (4) for air-tightly sealing the electrolytic solution injection port. A metal seal (2) is arranged between the electrolytic solution injection port (32) and the expansion plug (4). The metal seal (2) is of a metal containing aluminum as a main component, or a stainless steel, and the expansion plug (4) is of stainless steel.
