Abstract
An armouring material for use in an air secondary battery, including:
- an armouring sheet (2) constituted by laminating an outer layer (21) including heat-resistant resin film, a metal foil layer (22), and an inner layer (23) including a thermoplastic resin film, being equipped with an opening part (12) for taking oxygen in, perforating through the outer layer, the metal foil layer and the inner layer, and an oxygen-permeable membrane (3) being joined to the inner layer side in an opening part periphery (12a) and covering the opening part. The oxygen-permeable membrane is constituted from a porous fluororesin, a joining surface of outer periphery (3a) of the oxygen-permeable membrane is equipped with a primer layer (3c), and an adhesive layer (5) is provided at least in a space between the primer layer and the inner layer of the armouring sheet, to adhere the oxygen-permeable membrane to the armouring sheet.
