<P>PROBLEM TO BE SOLVED: To provide a base material-less double-sided pressure-sensitive adhesive sheet, capable of reducing a defect caused by deformation of an adhesive, reduced in a production loss in a process of separating a release film, and suitable for a touch panel, when used in the base material-less double-sided pressure-sensitive adhesive sheet for the electrostatic capacitance type touch panel. <P>SOLUTION: The base material-less double-sided pressure-sensitive adhesive sheet is prepared by laminating the release films on both faces of a pressure-sensitive adhesive layer having 100 μm or more of thickness, and one of the release films is provided with a release layer on a biaxially-oriented polyester film having 50 μm or more of thickness, and has a separation force in the range of 3-50 mN/cm. <P>COPYRIGHT: (C)2012,JPO&INPIT |
