A temperature control apparatus, in which it is intended to utilize a characteristic of a temperature detection device as it is for temperature detection over a wide range of changing temperature to thereby make it possible to control a unit by detecting a wide range of changing temperature of the unit using the single temperature detection device, comprising a temperature detection circuit for outputting a voltage corresponding to the resistance value of the temperature detection device whose resistance value varies with changes in temperature and processing means having a step acquiring the voltage, after A/D (analog-to-digital) converting the same, and then converting the voltage to a mathematically expressed temperature value using a predetermined relationship and a step performing process to execute temperature control using the temperature value obtained by the conversion.
