Pneumatic tire and manufacturing method of pneumatic tire

A pneumatic tire comprising:

• a non-conductive rubber layer constructing at least a tire outer circumferential side portion of a tread portion and formed by winding and laminating more than one non-conductive rubber ribbon along a tire circumferential direction;
• and
• a conductive layer provided in a part of the non-conductive rubber ribbon and continuously and spirally extending along the tire circumferential direction and spirally extending around a rotation axis of the tire,
• wherein the conductive layer is exposed on a tread surface and extends from a bottom surface of the non-conductive rubber layer, which is in contact with a base rubber layer, toward a tire outer circumferential side via a course extending continuously and spirally along the tire circumferential direction, and wherein a tire cross section comprises a plurality of pieces of the conductive layer scattered at various positions in the tire width direction and at various heights of the tire cross section and
• wherein the non-conductive rubber layer comprises at least two non-conductive rubber ribbons and is formed by continuously and spirally winding and laminating respectively a first non-conductive rubber ribbon in which a first conductive layer is provided in a part of the tire outer circumferential side portion of the first non-conductive rubber ribbon and a second non-conductive rubber ribbon in which a second conductive layer is provided in a part of the second non-conductive rubber ribbon such that the second conductive layer is in a different position from the first conductive layer in a tire radial direction when disposed side by side in the tire width direction, along the tire circumferential direction and at least one of the conductive layers is exposed on the tread surface.
