Abstract

A power storage device includes a positive electrode part including a first metallic foil layer and a positive electrode active material layer partially laminated on one surface of the first metallic foil layer, a negative electrode part including a second metallic foil layer and a negative electrode active material layer partially laminated on one surface of the second metallic foil layer, and a separator arranged between the positive electrode part and the negative electrode part. The positive electrode active material layer is arranged between the first metallic foil layer and the separator, and the negative electrode active material layer is arranged between the second metallic foil layer and the separator. The peripheral regions of the one surfaces of the first and second metallic foil layers in which the positive and negative electrode active material layers are not formed are joined via a peripheral sealing layer containing a thermoplastic resin.
