Abstract
A heating device () comprises: a heater () for heating an item (); a temperature detection unit () for detecting the temperature of the item (); and a temperature adjustment unit () for controlling the heater () on the basis of a target temperature and the detected value of the temperature detection unit () so that the temperature of the item () reaches the target temperature. The heating device () determines, as a system gain change rate, the rate of change from the initial value of a system gain determined as a ratio of a temperature increase value of the item () with respect to electric power inputted to the heater (), and determines the rate of change in the heat retention of the item () using the system gain change rate.
