Laminated body of rubber layers

A laminated body of rubber layers comprising:

• 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 formed from an adhesive rubber composition and being disposed between the resin layer and the rubber layer;
• the adhesive rubber composition containing 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) being formed from a modified butyl rubber (1) formed by reacting, with a butyl rubber, a compound (a) having in a molecule a nitroxide free radical that is stable at ambient temperature in the presence of oxygen, a radical initiator (b), and a co-crosslinking agent (c);
• and
• the modified rubber composition (B) being formed by compounding the co-crosslinking agent (c) with a modified butyl rubber (2) formed by reacting the compound (a) and the radical initiator (b) with the butyl rubber.
