To realize high temperature detecting precision required in a clinical thermometer, to shorten a measuring time, to accurately record temperature-detected data, and to finish storage work as a data.

This temperature measurement transceiver is combined with an antenna 18 for supplying a radio wave, an RF driver 16, an RF receiving circuit 17 for receiving a radio output and a temperature measuring transceiver provided with a liquid crystal display part 13, in a temperature measurement transceiver with an antenna 22 for receiving the radio wave, an electric power generation circuit 27 for conducting self-excitation power generation by rectifying the radio wave received by the antenna 22, a temperature sensor 25, and an RF part 21.
