Claim 0:
1. A laminated body comprising:
a metal foil layer including a first surface and a second surface on an opposite side of the metal foil layer from the first surface;
a heat-resistant resin layer including a stretched film;
a heat-sealable resin layer including an unstretched film having chemical resistance; and
a first adhesive agent layer interposed between the first surface of the metal foil layer and the heat-resistant resin layer, and a second adhesive agent layer interposed between the second surface of the metal foil layer and the heat-sealable resin layer; wherein
the first adhesive agent layer includes an adhesive agent section that adheres the metal foil layer to the heat-resistant resin layer, and an adhesive agent unapplied section, adjacent to the adhesive agent section, at which no adhesive agent is interposed between the metal foil layer and a corresponding portion of the heat-resistant resin layer such that the metal foil layer is exposed and not joined to the heat-resistant resin layer at the adhesive agent unapplied section;
the heat-resistant resin layer covers the first surface of the metal foil layer where the adhesive agent section is disposed, and nothing is disposed between the heat-resistant resin layer and the first surface of the metal foil layer at the adhesive agent unapplied section; and
the first surface of the metal foil layer is entirely covered by the heat-resistant resin layer, and the second surface of the metal foil layer is entirely covered by the heat-sealable resin layer.
