<p>A tire temperature sensor and a tire heat deterioration detection sensor capable of detecting a variation in the magnetic characteristics of a magnetic circuit structure or a composite magnet by a magnetic sensor for detecting magnetic field leaking from the magnetic circuit structure installed at the specific portion of a tire or a magnetic field from the composite magnet and formed so that the magnetic characteristics of the magnetic circuit structure or the composite magnet can be varied according to the temperature of the tire at the specific portion or the degree of heat deterioration, wherein the temperature of the tire at the specific portion is directly measured or the degree of the heat deterioration is directly detected by using the tire temperature sensor or the tire heat deterioration detection sensor so that an abnormality which may lead to the failure of the tire can be find out earlier, whereby the tire temperature sensor or the tire heat deterioration detection sensor capable of preventing a battery from being exhausted earlier can be provided.</p> |
