Provided is a pneumatic tire having an inner liner layer which is formed from a laminate sheet produced by laminating a sheet comprising a thermoplastic resin or a thermoplastic resin composition comprising a blend of a thermoplastic resin and an elastomer on a rubber capable of cure-adhesion to the thermoplastic resin or the thermoplastic resin composition, whereby it becomes possible to provide the tire that does not undergo the cracking in the vicinity of a splice part of the inner liner layer after the initiation of running of the pneumatic tire and therefore has excellent durability. A pneumatic tire produced by laminating a sheet (2) which comprises a thermoplastic resin or a thermoplastic resin composition comprising a blend of a thermoplastic resin and an elastomer on a rubber (3) which is capable of cure-adhesion to the thermoplastic resin or the thermoplastic resin composition to produce a laminate sheet (1) and lap-splicing an end part of the laminate sheet (1) to form an inner liner layer (10), wherein, in the sheet (2) comprising the thermoplastic resin or the thermoplastic resin comprising the blend of the thermoplastic resin and the elastomer to be used, the tip of the end part is sharpened.
