A power supply unit is for an inhalation device and is controlled so as to flexibly respond to the detection of a temperature anomaly in the controller. A power supply unit is provided to an inhalation device and includes; a battery; a controller that controls the charging operation of the battery as well as the discharging operation f the battery when the source of an inhalation component is vaporized or atomized; and a temperature measurer that measures the temperature of the controller. The controller causes the temperature measurer to measure the temperature of the controller in a first cycle during the charging operation and in a second cycle during the discharging operation, and assesses the temperature state of the power supply unit in accordance with the measurement results.
