Method of manufacturing laminated armoring material

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 second adhesive agent layer includes an adhesive agent section that adheres the metal foil layer to the heat-sealable 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-sealable resin layer such that the metal foil layer is not joined to the heat-sealable resin layer at the adhesive agent unapplied section;
• the heat-sealable resin layer covers the second surface of the metal foil layer where the adhesive agent section is disposed;
• 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.
