摘要:
The present invention relates to a reliable transponder 3 for a tire and a reliable transponder-provided tire which are not broken while the tire runs or the tire is formed or cured, by using various metallic component members used in the tire as an antenna directly connected to the transponder 3 and thereby, further decreasing the transponder 3 in size. For example, by electrically directly connecting the transponder 3 with a conductive wire 131 or bead wire 161 in a jointless belt 13A set to the inner and outer peripheries of the tire, the wire 131 or bead wire 161 is used as the receiving and transmitting antenna of the transponder 3. Thereby, it is possible to decrease the transponder 3 in size and to increase the communication distance between an interrogator and the transponder 3 without increasing the transmission power of the interrogator.
