Abstract
A method is provided for adhering prescribed adherend rubbers to one another using a rubber for adhesion obtained from a rubber composition for adhesion containing an ethylene-α-olefin copolymer (X2) and an organic peroxide (Y2) at the adhesion interface between the adherend rubbers. The ethylene-α-olefin copolymer (X2) contained in the rubber composition for adhesion contains an ethylene-1-butene copolymer. The ethylene-1-butene copolymer satisfies prescribed values of the number average molecular weight and the molecular weight distribution. The content of the ethylene-1-butene copolymer is from 60 to 100 mass % of the total mass of the ethylene-α-olefin copolymer (X2).
