Claim:
1. A gas barrier pressure-sensitive adhesive sheet comprising at least one gas barrier layer, at least one pressure-sensitive adhesive layer, and at least one release sheet, wherein the at least one pressure-sensitive adhesive layer has a storage modulus at 23° C. of 2.0×10 the gas barrier pressure-sensitive adhesive sheet having a substantial thickness of 0.5 to 50 μm, and other than the release sheet, each layer included in the gas barrier pressure-sensitive adhesive sheet does not satisfy either requirement 1 or 2: requirement 1: a paper or a plastic film having a thickness of 10 μm or more; and requirement 2: a plastic film having a tensile modulus at 23° C. of 200 to 5000 MPa.
