In general, in one aspect, embodiments disclosed herein relate to a heating control device including a transistor configured to supply electric power by switching operation to a heater that heats a coolant. The heating control device adjusts a heating amount from the heater based on a heating amount control profile. The heating amount control profile includes a decrease portion in which the heating amount decreases as the temperature of the coolant increases. The decrease portion includes a first decrease portion and a second decrease portion each having a negative slope, and the first decrease portion and the second decrease portion have the same heating amount at a target temperature. The first decrease portion includes a first region and a second region, and as negative slopes, a slope at any temperature in the second region is larger than a slope at any temperature in the first region.
