PROBLEM TO BE SOLVED: To prevent the electrification up to the end ofd traveling by applying a conductive rubber layer having a specific resistivity value and a prescribed physical property to a prescribed position of a treated part to form an energized path. SOLUTION: In this pneumatic tire, a conductive rubber layer 2 is present on the cap layer 1 of a tire tread having a resistivity value of 10<8>Ω.cm or more so as to be circumferentially continued from the tread to a base layer 3. The rubber layer 2 has a center X ranging from W/4 or more to 3W/4 or less to the direction of tread width W. When X is within this range, the conductive rubber layer 2 is surely situated in grounding area, and a sufficient electrification effect can be provided. The thickness after vulcanization of the conductive rubber layer 2 is set to 0.5 mm or more, more preferably, 1.0-2.0 mm, considering the durability to the end of traveling.
