Pneumatic tire, producing method of pneumatic tire, and forming apparatus of rubber strip winding body

A pneumatic tire (1) comprises a tread conductive part which is disposed on an inner side of a tread portion (2), and a tread rubber portion (22) comprising a rubber strip winding body in which a rubber strip (25) is spirally wound and superposed in a circumferential direction. A radially outer surface of the tread rubber portion forms a tread-ground contact surface, and a radially inner surface of the tread rubber portion is in contact with the tread conductive part. At least one surface of the rubber strip (25) is formed with a conductive film (26) made of conductive material. An outer edge (26a) of the conductive film appears on the tread-ground contact surface, and an inner edge (26b) of the conductive film is in contact with the tread conductive part so that the conductive film forms a conductive path (27).
