A load drive controller for controlling a heat generating member by a switching element includes a temperature detection portion for detecting a physical quantity of a level corresponding to a temperature of the switching element, a protection function portion for outputting an abnormality signal corresponding to an overheated state of the switching element when the physical quantity detected by the temperature detection portion is larger than a valu e, a control portion for causing the heat generating member to generate heat by driving the switching element via a driving portion. Furthermore, the control portio n causes a temperature adjustment portion to increase the temperature of the heat generating member when the abnormality signal is input from the protection function portion.
