る。Conventional technology In recent years, as equipment that operates using batteries as a power source has become smaller and thinner, we have synthesized a power generation element consisting of a thin positive electrode, negative electrode, and separator to meet the demand for smaller and thinner batteries. There are batteries covered with a resin sheet. In such batteries, the synthetic resin coated is often a single layer synthetic resin, which is bonded and sealed at the outer periphery of the power generating element.

複雑となり、非常にやっかいである。In addition, if a negative electrode active material such as lithium is used, which is highly reactive with water and oxygen, the battery must be completely closed to prevent water (water vapor) and oxygen from entering, from the viewpoint of lithium deterioration and safety. In such a case, a structure in which the terminal protrudes makes sealing the terminal portion complicated and very troublesome.
しかも、このような突出した構造の端子が存在すること

を有している。Means for Solving the Problems The battery of the present invention is a battery constructed by covering an electrode plate group consisting of a positive electrode, a negative electrode, and a separator with a pair of sheet-like or film-like synthetic resin. The synthetic resin covering the laminate has a laminate structure consisting of multiple layers, and at least one metal layer is placed on the surface of the laminate structure, and the metal layer covers the entire area of the synthetic resin except for the peripheral area. The synthetic resin has a laminated structure and has at least two or more through holes for conducting electricity.
