An object of the present invention is to provide a resin composition which is excellent in gas barrier properties, mechanical strength and elasticity, and which is less deformed by its own weight even under high temperature conditions and exhibits low contamination. The present invention contains an isobutylene polymer (A) having a number average molecular weight and a weight average molecular weight of 20,000 to 200,000, and the content of a component having a molecular weight of less than 10,000 is less than 5% by weight. The thermoplastic resin composition characterized by these. |
