Abstract
A patterned pressure-sensitive adhesive tape includes a pressure-sensitive adhesive layer. The pressure-sensitive adhesive layer is formed by a pressure-sensitive adhesive composition for patterned pressure-sensitive adhesive tape. An elongational viscosity of the pressure-sensitive adhesive composition measured at 30° C. is 1,000 mPa·s or greater and 650,000 mPa·s or less, or a Trouton's ratio thereof measured at 30° C. is 8 or greater and 400 or less. The pressure-sensitive adhesive layer has two or more pressure-sensitive adhesive portions (B) and a non-pressure-sensitive adhesive portion region having no pressure-sensitive adhesive portions (B) between the two or more pressure-sensitive adhesive portions (B). The non-pressure-sensitive adhesive portion region is patterned to lead to an outer periphery of a sheet plane.
