Claims

[Scope of utility model registration request]

In a thin battery in which a power generation element is housed between two metal plates, and the peripheral parts of both metal plates are fused and sealed with a heat-sealable material made of hot melt adhesive, both of the metal plates are placed in the peripheral part of the battery. 1. A thin battery characterized in that a metal foil having a U-shaped cross section extending between the metal foils is fixed to the metal foil through a heat-sealable material similar to the above.
