PROBLEM TO BE SOLVED: To provide a temperature abnormality alarm device capable of allowing the early detection of an abnormality which may cause a tire failure by directly measuring a temperature in a rubber member inside the tire. SOLUTION: The temperature abnormality alarm device 10 comprises a tire temperature measuring apparatus 7, a temperature abnormality determining means 8, and a temperature abnormality indicating means 9. The tire temperature measuring apparatus 7 generates an eddy current in a predetermined part P of a conductive member such as a steel belt B constituting the tire T, measures a current induced in a measuring coil 1 arranged outside the tire T by magnetic flux induced by the eddy current, and determines the temperature of the rubber member near the predetermined part by converting this current value to the temperature based on a predetermined conversion equation.
