A tire has a cap rubber formed of nonconductive rubber and forms a ground surface, and a conductive portion provided in at least one side end portion of a pair of side end portions in both ends in a tire width direction. The conductive portion is formed of a conductive rubber, and reaches a side surface of the cap rubber from the ground surface through an inner portion of the cap rubber. The conductive portion is relatively small in a thickness in the ground surface and a side surface of the cap rubber, is relatively large in the maximum thickness of an intermediate portion between the ground surface and the side surface of the cap rubber, and is formed into a crescent shape which is curved into an outer side in a tire width direction and an outer side in a radial direction, in a tire meridian cross section.
