Claims

[Scope of utility model registration request]

A flat battery in which a current collector is interposed between the inner surface of a metal can and a battery active material loaded therein, and the battery active material is tightly pressed onto the current collector, and the current collector is 1. A flat battery whose body is made of expanded metal having a substantially diamond-shaped pattern, and the diagonal width of the diamond-shaped pattern in the stretching direction is larger than the diagonal width in the slit direction.
