PROBLEM TO BE SOLVED: To provide a piston temperature measuring device which uses an electromagnetic induction method and assures strengths of a fixing side module and a moving side module. SOLUTION: (1) The piston temperature measuring device comprises: the fixing side module 20 equipped with a transmitting coil 21, a receiving coil 22, a ferrite core 23 and a stay 24; and the moving side module equipped with a resonance coil. The stay 24 of the fixing side module 20 has a structure which is divided into two portions and holds the ferrite core 23 while sandwiching it. (2) The one side surface of a sandwiching section in the two-divided structure of the stay 24 which sandwiches the ferrite core, is made flat, and the other side surface is made triangular. (3) The fixing side module 20 has a relay element 23 which is arranged between an external wire 50 disposed outside the fixing side module 20 and the transmitting coil 21 and the receiving coil 22, and the relay element 23 is interposed between the two-divided stay 24.
