Abstract

A power supply unit for an aerosol inhaler, which includes a power supply configured to discharge electricity to a load that is configured to heat an aerosol generation source and has a correlation between temperature and electric resistance values, includes: a first element connected in series to the load and having a first electric resistance value; a second series circuit that includes a second element having a second electric resistance value, and a third element 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 including the load and the first element; and an operational amplifier 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.
