Abstract: A double-sided adhesive tape has an adhesive member which is formed in the shape of a film and whose both surfaces in a thickness direction have an adhesive force and a pair of separation films which are arranged so as to sandwich the adhesive member in the thickness direction. The double-sided adhesive tape is formed so as to have a non-planar shape and to reduce the occurrence of wrinkles in the adhesive member when the adhesive member is adhered to a non-planar adherend.

Abstract: This invention provides a PSA sheet that allows prevention or reduction of damage such as fracture with efficient stretch removability. A stretchable PSA sheet is provided, comprising a PSA layer and a film-like substrate supporting the PSA layer. The PSA sheet has a long section. The long section has a tapered segment that extends, tapering to a first end of the length direction and the film-like substrate has a minimum cross-sectional area larger than 0.30 mm2 in the tapered segment.
