To provide an air-permeable sheet made of a thermoplastic resin excellent in tensile strength, having air permeability along with water barrier properties and fitted as a cover at the time of casting of concrete and a sealing sheet at the time of repairing of a concrete structure.

This air-permeable sheet made of the thermoplastic resin is constituted by laminating a cloth-like material, which is formed by crossing uniaxially stretched linear materials comprising the thermoplastic resin, on one side or both sides of a nonwoven fabric made of the thermoplastic resin and applying a large number of pressure-sensitive adhesive stripes to the surface of the cloth-like material on one side of the obtained laminated sheet.
