PURPOSE: A piston temperature measurement apparatus is provided to precisely and stably measure a temperature of a piston by minimizing an influence exerting on a movement of a piston. CONSTITUTION: A piston temperature measurement apparatus includes at least one thermocouple(111-118) so as to measure a temperature from at least one part of a piston. The thermocouples(111-118) are connected to a wireless measurement unit(105). The wireless measurement unit(105) measures the temperature of the piston based on voltage signals generated from the thermocouple(111-118). The wireless measurement unit(105) is provided at an inner portion thereof with an isothermal block(120) and cold junctions of the thermocouples(111-118) are installed in the isothermal block(120). A cold junction temperature detector is provided to measure the temperature of the isothermal block(120).
