To improve the adhesiveness of an air permeation suppressing film to a rubber member or a rubber layer to be laminated with, without the need of forming an additional adhesive layer or addition of a third ingredient deteriorating characteristics of the film to the film.

A pneumatic tire includes, as an inner liner 8, the air permeation suppressing film F having a sea-island structure with an air-permeation-resistant resin ingredient P as sea phase and a rubber ingredient E containing a diene type rubber as island phase. One side of the air permeation suppressing film F is surface-treated to make the rubber ingredient E of the island phase exposed to the surface. The surface-treated surface is adhered to an unvulcanized rubber layer 6 formed on the side of the inside surface of the tire and composed of the diene type rubber, and the exposed rubber ingredient E and the rubber layer 6 are co-bridged during vulcanization molding of the tire to adhere the air permeation suppressing film F to the rubber layer 6.
