Abstract

A cell device comprises a cell case made of a sheet for cell cases, a cell housed in the cell case, and tabs projecting from the cell case. The sheet comprises a first base film layer, a metal foil layer, and a thermally adhesive resin layer formed in order of mention from the outside. The first base film layer is made of a biaxially oriented polyethylene terephthalate film or a biaxially oriented nylon film. The metal foil layer is made of an aluminum or copper film. The thermally adhesive resin layer is made of polyolefin resin, especially of acid-modified polyolefin resin.
