Abstract

This inhalation device is provided with: a power source unit for supplying power; a heating unit for using power supplied from the power source unit to heat a substrate containing an aerosol source; a measurement unit for measuring a measurement value corresponding to the temperature of the heating unit; an operation unit, which is different from the heating unit, that runs on power supplied from the power source unit; and a control unit for controlling operation of the heating unit on the basis of heating settings stipulating a time series transition in a target temperature that is a target value for the temperature of the heating unit. The control unit implements correction processing to correct the measurement value in response to the start of power supply to the operation unit from the power source unit.
