To provide a pneumatic tire that is formed by using a resin film sheet in which a thermoplastic elastomer composition including a thermoplastic resin or a blend of a thermoplastic resin and an elastomer is made into a sheet shape, forming the sheet into a cylindrical shape by connecting end portions of the sheet by an overlap splice method, subjecting the sheet to vulcanization molding, and using the sheet as an inner liner layer or a reinforcing layer, wherein the pneumatic tire has excellent moldability and durability without generating a crack near a connecting portion of the resin film sheet during a molding process of the pneumatic tire and after starting running of the pneumatic tire. The pneumatic tire of the present invention has an overlap splice portion joined by overlapping resin film sheet materials on each other, wherein at least one layer of two layers joined by overlapping the film sheet materials in the overlap splice portion has recessed portions of a depth D (µm) that is smaller than a thickness T (µm) of the film sheet material on a non-joining surface side thereof, and joining surface sides of the two layers are formed into flat surfaces and the flat surfaces are joined.
