Abstract
A structure that is constituted by disposing a laminate film and a collector rubber with a metal terminal plate interposed therebetween and a structure that is constituted by disposing a laminate film and a collector rubber with a metal terminal plate interposed therebetween are disposed so as to sandwich a fundamental cell that is constituted by disposing a positive electrode layer and a negative electrode layer, respectively, on surfaces of a separator, the laminate films are fusion bonded at peripheries thereof, and thereby the fundamental cell is sealed in a package cell. In the laminate film, a window portion or an opening is disposed, and a metal terminal plate is partially exposed and used as an external connection terminal. Owing to this configuration, a laminate film packaged storage device in which sealing properties and the volume efficiency are improved can be provided.
