Provided is a rubber laminate which is improved in adhesion between a resin layer (3) and a rubber layer 2 in comparison to conventional ones. This rubber laminate is obtained by interposing an adhesive layer (3), which is formed of an adhesive rubber composition, between the resin layer (3) that is formed of a polyester resin or a polyamide resin and the rubber layer 2 that is formed of a rubber composition containing a diene rubber. This rubber laminate is characterized in that: the adhesive rubber composition contains a modified rubber composition (A) or (B) having a number average molecular weight of 70,000-110,000; the modified rubber composition (A) is composed of a modified butyl rubber (1) that is obtained by reacting a butyl rubber with a compound (a) having a nitroxide free radical in each molecule, said nitroxide free radical being stable at room temperature in the presence of oxygen, a radical initiator (b) and a co-crosslinking agent(c); and the modified rubber composition (B) is obtained by blending the co-crosslinking agent(c) into a modified butyl rubber (2) that is obtained by reacting a butyl rubber with the compound (a) and the radical initiator (b).
