To provide a transponder for tire, in which the physical quantity in an atmosphere within a tire air chamber can be accurately detected by a sensor and which can be vulcanized in a state in which it is embedded in the tire, a tire with the transponder, and a manufacturing method of the tire. According to the present invention, a transponder obtained by hermetically sealing, by a housing, a circuit substrate with the sensor and other electronic components packaged is embedded between an inner liner and a carcass ply. A green tire thus embedded is vulcanized, and after the vulcanization, the tip end portion of a protruded portion of the housing is removed together with part of the tire inner wall surface, and an aperture is formed at a tip end of the protruded portion to communicate an interior of the tire air chamber with the sensor within the housing. Since a circuit substrate is hermetically sealed and housed within the housing, there is no possibility that pressure during vulcanization is applied to the sensor. Thereby, the sensor and the electronic components are protected against deterioration and destruction due to the pressure during vulcanization.
