Abstract

A sheet-type cell disclosed in this application includes an outer case and a power generation element contained in the outer case. The power generation element includes a positive electrode, a negative electrode, a separator, and an electrolyte solution. The separator is constituted by a porous resin sheet. The outer case includes a first outer case member and a second outer case member. Each outer case member includes a thermally fusible resin layer. The first outer case member and the second outer case member are disposed on respective opposite sides of the power generation element. A periphery of the first outer case member and a periphery of the second outer case member are sealed by thermally welding, with a periphery of the separator interposed between the peripheries of the first and second outer case members.
