Claims

[Scope of utility model registration request]

Active material layers such as a negative electrode layer and a positive electrode mixture layer are laminated via a separator, and a flat power generation element is formed by contacting a current collector plate to the surface of each of the active material layers, and is covered with an exterior film from above and below. In a thin battery formed by thermally welding the peripheral edges of the outer film to each other via a frame-like frame, at least one current collector plate is made larger in size than the active material layer with which it is in contact; A thin battery characterized in that the peripheral edge of the current collector plate on the inside surface of the battery is surrounded by the frame-like frame.
