Abstract
A pressure-sensitive adhesive sheet includes a pressure-sensitive adhesive layer and a substrate layer configured to support the pressure-sensitive adhesive agent layer. The pressure-sensitive adhesive layer has a storage modulus of 250 kPa or less at 23° C. The substrate layer has an elastic modulus of 1680 N/cm to 3000 N/cm both inclusive. The pressure-sensitive adhesive sheet shows a deviation amount less than 1.0 mm. The amount is the deviation amount of the pressure-sensitive adhesive sheet per 250 gf/cm2 of the sheet in a holding ability test at 80° C. after one hour from a time when the test is started.
