Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a pneumatic tire having a plurality of film layers made of thermoplastic resin or thermoplastic elastomer composition, and used to form an air-impermeable layer, improving uniformity while improving a problem with the number of reinforcing cords per unit length of a carcass layer becoming uneven in the circumferential direction of the tire. SOLUTION: The pneumatic tire includes the air-impermeable layer 9 disposed inside the carcass layer 4 arranged with the reinforcing cords, wherein the air-impermeable layer 9 includes a plurality of film layers 9A, 9B made of thermoplastic elastomer composition composed of a blend of a thermoplastic resin or a thermoplastic resin component and a thermoplastic elastomer component. At least one layer of the plural film layers 9A, 9B includes the seamless cylindrical film layer 9A. COPYRIGHT: (C)2010,JPO&INPIT
