Abstract
A pressure-sensitive adhesive tape () has a base material (), and a pressure-sensitive adhesive layer () provided on the surface (A) of the base material () and containing cells () in the inside thereof, wherein the cells () include first cells (A) contacting with the surface (A) of the base material () and second cells (B) disposed at positions away from the surface (A) of the base material (). Thereby, even when the cells () are made to be much contained in the pressure-sensitive adhesive layer () and the amount of a pressure-sensitive adhesive is made small, a high pressure-sensitive adhesive performance of the pressure-sensitive adhesive tape () is retained.
