Claims

[Scope of utility model registration request]

A single film-like exterior body having a first surface portion and a second surface portion provided with positive and negative terminal holes is bent at the center to form the first and second surfaces through a bent portion at the center. A flat battery in which three peripheral parts of the surface part of the battery are bonded to each other and a flat power generating element is sealed inside the film, and the first battery is arranged such that the terminal hole of one of the pressure and negative electrodes is closed. A current collector having a constant width is disposed from a surface portion of the exterior film to a second surface portion, and the surface portion of the current collector at least on the second surface portion of the exterior film is covered with an insulating sheet; 1. A flat battery comprising: a current collector disposed so as to be isolated from the current collector at a portion thereof and to close the other terminal hole.
