An object of the present invention is to make it possible to efficiently and easily volatilize a room-temperature volatile chemical when necessary, without causing thermal decomposition or scattering of the normal-temperature volatile chemical during production. Provided is a cold-gas-dissipating substance whose temperature can be controlled arbitrarily. A drug-containing pressure-sensitive adhesive layer containing a room-temperature-volatile chemical is laminated on at least one surface of a base material layer, and a peelable protective film layer is further laminated on the surface.
