<p>[Problem] To provide a laminate pack battery which has sealing reliability as before even if the width of a sealing portion is reduced. [Solution] A laminate pack battery of the present invention contains an electrode body within an internal space that is formed between first and second metal laminate sheets, each of which is obtained by laminating a metal layer and a resin layer, and the resin layers in the peripheries of the first and second metal laminate sheets are thermally welded with each other and sealed, thereby forming a sealing portion. The laminate pack battery is characterized in that a sealing member that has a melting point equal to or lower than that of the resin layers is disposed from a space between the first and second metal laminate sheets in the sealing portion to the internal space formed by the first and second metal laminate sheets and the sealing member is welded with the resin layers of the first and second metal laminate sheets.</p> |
