An object of the present invention is to provide a manufacturing method of a pneumatic tire capable of appropriately maintaining electrical conductivity performance and satisfactorily exerting improvement effect obtained by using a tread rubber blended with silica at a high ratio, and to provide such a pneumatic tire. To achieve the above object, the method of manufacturing a pneumatic tire according to the present invention comprises a step of forming an electrically non-conductive tread rubber that constitutes an outer periphery portion of the tread and a step of forming an electrically conductive layer that extends along the circumferential direction of the tire formed on the tread surface while changing the position in a width direction of the tire so as to alternately pass through a first position and a second position, and a step of forming the outer end of the sidewall rubber as viewed in a tire-diameter direction disposed on an imaginary extension line or at a point that is outer than the imaginary extension line as viewed in a tire-diameter direction, the imaginary extension line extending outwardly from a point of 15% depth of wear limit depth in a shoulder portion along the tread surface in a width direction of the tire, as well as at a point that is located at an outer side than the ground contact end as viewed in a width direction of the tire.
