PROBLEM TO BE SOLVED: To provide a more excellent and firm encapsulation method, and a more excellent method that provides an electrical conductive contact containing more remarkably thin encapsulation than a publicly-known encapsulation method while being firm to physical impacts.SOLUTION: A battery has a first electrical contact, a coupling layer which is joined to the first electrical contact and has a buried conductor, at least one cell structure and a second electrical contact. The coupling layer and the at least one cell structure are sandwiched between the first electrical contact and the second electrical contact, and the coupling layer has plural layers formed of different materials. The plural layers contain lower layers which are in contact with the cell structure, and the lower layers are chemically adaptable to the cell structure. The plural layers contain upper layers which are in contact with the first electrical contact. The upper layers have high melting point and high stress elasticity. The lower layers are arranged below the upper layers, and the upper layers of the coupling layer has polyamide or the like.SELECTED DRAWING: None |
