Claims

[Scope of utility model registration request]

A flat battery in which a power generating element is sealed by a jacket material made of a thin metal plate and a resin layer covering the top and bottom of the metal plate, and a terminal plate is exposed through a cutout window provided in the jacket material, the peripheral edge of the window being exposed. An insulating layer is interposed between the outer covering material and the terminal board,
Furthermore, the flat battery has an insulating layer covering an end face portion of the outer covering material exposed to the window.
