<p>Provided is a substrate-less, double-sided, pressure-sensitive adhesive sheet which minimizes the flaw resulting from foreign matter(such as oligomer) generated in a manufacturing step and thus exhibits excellent optical inspectability and which achieves a high yield in a step of laminating the pressure-sensitive adhesive sheet on other member and thus ensures high productivity. A substrate-less, double-sided, pressure-sensitive adhesive sheet obtained by laminating a first release film on one surface of a pressure-sensitive adhesive layer and laminating a second release film on the other surface thereof, wherein the first release film is a biaxially oriented polyester film having a release layer which comprises both a silicone resin that has alkenyl and alkyl groups as functional groups and that contains a migratory component and a platinum-based catalyst and which exhibits a residual adhesion ratio of 60 to 90%, a low-speed peel force of 10 to 20mN/cm at a peel rate of 300mm/min, a high-speed peel force of up to 2.5 times the low-speed peel force at a peel rate of 10000mm/min, and a Martens hardness of 400N/mm2 or higher as determined with a 115° triangular pyramid indenter and a test force of 0.10mN.</p> |
