A heater unit that much improves accuracy in thermal uniformity of an object of heating during cooling, particularly rapid cooling, is provided. The heater unit in accordance with the present invention includes a heater substrate for mounting an object of heating and performing heat treatment thereon, and a cooling module for cooling the heater substrate, and between said heater substrate and the cooling module, an intervening body is arranged. Utilizing deformability of the intervening body, ratio of a non-contact portion can be reduced than when the intervening body is not provided, and temperature uniformity of the heater substrate at the time of cooling can be improved.
