Abstract
A pressure-sensitive adhesive layeris formed on a release treated surface of a release liner, and gas from holesin the release lineris made to move to the outside of the pressure-sensitive adhesive layer, thus forming through holesin the pressure-sensitive adhesive layer. The pressure-sensitive adhesive layerand a base materialhaving provided therein gas-passing channels that communicate to the outside of the pressure-sensitive adhesive sheet are then laminated together such that the gas-passing channels in the base materialand the through holesin the pressure-sensitive adhesive layercommunicate with one another, thus obtaining a pressure-sensitive adhesive sheet. According to the pressure-sensitive adhesive sheet, air entrapment and blistering can be prevented or eliminated while securing adequate adhesive strength and with no marring of the appearance.
