  "textContent": "A power supply unit for an aerosol inhaler including a load 21, which heats an aerosol generation source and whose temperature and electric resistance value have a correlation. The power supply unit includes: a first series circuit having a first element 63 with a first electrical resistance R1 connected to the load 21; a second series circuit having a second element 64 with a second electric resistance R2 and a third element 65 with a third electrical resistance R3, and connected in parallel with a first series circuit; and an operational amplifier 56 in which one of a non-inverting input terminal and an inverting input terminal is connected to the first series circuit, and the other of the non-inverting input terminal and the inverting input terminal is connected to the second series circuit. Each of the first, second and third resistance values are larger than the electric resistance value RH of the load at a normal temperature or a temperature in a predetermined temperature range.",
