A process includes (i) the steps of adhering a pressure-sensitive adhesive layer supported on a base material to a release layer containing a mixture of a polyethylene and an ethylene/alpha-olefin copolymer and aging the resultant structure at 40 to 75° C. for 6 hours or more or (ii) the steps of adhering a pressure-sensitive adhesive layer supported on a base material to a release layer containing a linear ethylene-based resin in which the content of components eluted at 30° C. or lower measured by the temperature rising elution fractionation method is 3 to 30 wt % and aging the resultant structure at 55 to 75° C. for 6 hours or more, to thereby regulate the pressure-sensitive adhesive layer so as to have a peel force of 0.5 to 5 N/50 mm when peeled from the release layer at an angle of 180° and a rate of 2 m/min together with the support base material.
