Abstract

A thin-type battery includes: a flat shaped electrode body formed by stacking a positive electrode and a negative electrode while interposing a separator in between; an electrolyte; and an exterior body made from a laminate film, the exterior body enclosing the electrode body and the electrolyte with ends of the exterior body being hermetically sealed by heat-sealing, wherein the exterior body includes a folded part to be folded from one surface side to another surface side of the electrode body and to extend along an edge of the electrode body, and the folded part includes resin-interposed heat-sealing portions located in regions in two ends in a direction along the edge of the electrode body and outside the electrode body, where portions of the exterior body are opposed to each other, each resin-interposed heat-sealing portion being heat-sealed by interposing a piece made from a resin.
