Abstract

A laminated body of rubber layers includes: a resin layer formed from a polyester resin or a polyamide resin; a rubber layer formed from a rubber composition containing a diene rubber; and an adhesive layer disposed between the resin layer and the rubber layer. The adhesive rubber composition contains a modified rubber composition (A) or a modified rubber composition (B) both having a number average molecular weight of 70,000 to 110,000. The modified rubber composition (A) is formed from a modified butyl rubber (1) formed by reacting, with a butyl rubber, a compound having in a molecule a nitroxide free radical that is stable at ambient temperature in the presence of oxygen, a radical initiator, and a co-crosslinking agent. The modified rubber composition (B) is formed by compounding the co-crosslinking agent with a modified butyl rubber (2) formed by reacting the compound and the radical initiator with the butyl rubber.
