POWER SUPPLY UNIT FOR AEROSOL INHALER

A power supply unit for an aerosol inhaler, which includes a power supply (12) configured to discharge electricity to a load (21) that is configured to heat an aerosol generation source and has a correlation between temperature and electric resistance values, includes a first element (63) connected in series to the load and having a first electric resistance value, a second series circuit (C2) that includes a second element (64) having a second electric resistance value, and a third element (65) connected in series to the second element and having a third electric resistance value, the second series circuit being connected in parallel with a first series circuit (C1) including the load and the first element and an operational amplifier (56) connected to the first series circuit and the second series circuit. The first electric resistance value is less than an electric resistance value of the load.
