PROBLEM TO BE SOLVED: To provide a pneumatic tire having a simple structure and capable of efficiently discharging the static electricity in a vehicle to a road surface. SOLUTION: A plurality of conductive rubber members 20 having the electric resistance lower than that of a tread rubber body 11a are embedded in the tread rubber body 11a with a spacing in the tire circumferential direction, outer ends 20a in the radial direction of these conductive rubber members 20 are exposed to a tread face 11c of an outer circumferential surface of a tread part, and inner ends 20b in the radial direction are brought into contact with a conductive rubber layer 11b provided on a steel belt layer 15 provided inward of the tread part 11 in the tire radial direction, or between the tread rubber body 11a and the steel belt layer 15. The conductive rubber members 20 have a shape to be driven in from the outer circumferential surface of the tread rubber body 11a. COPYRIGHT: (C)2007,JPO&INPIT
