Claims

[Scope of utility model registration request]

The positive electrode mixture is contained in a sealed case formed by tightly fixing a positive electrode can and a lid body having an insulating cap with a negative electrode terminal inserted therethrough in a hermetically insulating manner and having a falling part on the inner surface of the lid. A battery containing a battery structure formed by laminating a separator and a negative electrode, characterized in that the lower end of the falling part of the insulating cap is pressed against the positive electrode mixture without intervening a separator. .
