POWER SUPPLY UNIT FOR AEROSOL GENERATION DEVICE

A power supply unit includes: a power supply configured to discharge electricity to a first load and a second load; a circuit element; a switching element configured to be switchable between a first state where the circuit element and the first load are connected in series and a second state where the circuit element and the second load are connected in series; an operational amplifier to which a voltage applied to the first load in a first series circuit formed of the circuit element and the first load in the first state is input, and to which a voltage applied to the second load in a second series circuit formed of the circuit element and the second load in the second state is input; and a processing device configured to detect a temperature of each of the first and second loads based on output of the operational amplifier.
