Provided is a pressure-sensitive adhesive sheet for conveying an electrolyte membrane capable of contributing to improving a handling property at the time of conveyance of a polymer electrolyte membrane, and to preventing deformation of the polymer electrolyte membrane and preventing the occurrence of a wrinkle therein during processing of a membrane electrode assembly (MEA). The pressure-sensitive adhesive sheet for conveying an electrolyte membrane of the present invention includes: a base material; and a pressure-sensitive adhesive layer arranged on one surface or each of both surfaces of the base material, in which the pressure-sensitive adhesive layer has a pressure-sensitive adhesive strength which lowers or disappears through an external stimulus. In one embodiment, the pressure-sensitive adhesive layer contains thermally expandable microspheres.
