Polymer laminate and pneumatic tire using the same as inner liner

An object of the present invention is to provide a polymer laminate that has a small thickness and is excellent in air permeation resistance and adhesion with an adjacent rubber, and a pneumatic tire using the same as an inner liner. A polymer laminate (10c) includes a first layer (11c) having a thickness of 0.05 mm to 0.6 mm made of a styrene-isobutylene-styrene triblock copolymer, and a second layer (12c, 13c) containing at least one of a styrene-isoprene-styrene triblock copolymer and a styrene-isobutylene diblock copolymer, and a second layer (12c, 13c) have a thickness of 0.01 mm to 0.3 mm.
