The pressure-sensitive adhesive sheet includes a pressure-sensitive adhesive layer, and a substrate layer configured to support the pressure-sensitive adhesive 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 1,680 N/cm to 3,000 N/cm. The pressure-sensitive adhesive sheet shows a deviation amount less than 1.0 mm, the amount being 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 holding ability test is started. Helium gas is accommodated in a cavity defined by the base and the cover.
