A pneumatic tire is vulcanized using a bladder provided with a coating layer formed of a release agent, and includes a sealant layer disposed on an inner surface of a tread portion in a tire circumferential direction. The amount of silicon of the release agents detected in at least a placement region of the sealant layer by fluorescence X-ray analysis is from 0.1 wt. % to 10.0 wt. %.
