Provide a body temperature measuring apparatus 1 which can measure body temperature with high accuracy, is a non-battery type and a non-contact type, and realize improvement in accuracy in measuring body temperature with software version upgrades easily. A body temperature measuring apparatus is comprised of a terminal apparatus 10 and a body temperature detection unit 11. The body temperature detection unit 11 comprises a power supply unit 11b for converting a voice output signal from the terminal apparatus into electricity, a detection unit 11c for detecting infrared energy from the user's skin surface as a temperature detection signal, and a conversion unit 11d for converting the temperature detection signal into a voice input signal. The terminal apparatus 10 comprises a oscillation means for oscillating a voice output signal to the body temperature detection unit 11, and a measurement means for estimating the user's body temperature corresponding to the surface temperature of which the variation is small based on the voice input signal received form the body temperature detection unit 11, an emissivity of the user's skin surface, and the temporal variation of the surface temperature calculated within a predetermined measurement time. |
