Abstract: A power supply unit for an aerosol inhaler includes: a power supply configured to supply power to a load that atomizes an aerosol source; a temperature sensor configured to acquire a temperature of the power supply; a controller; and a circuit board on which a plurality of elements including the temperature sensor and the controller are mounted. The circuit board includes a first surface and a second surface which is a reverse surface from the first surface or is located on a side opposite from the first surface. The plurality of elements are mounted on each of the first surface and the second surface. The second surface faces the power supply, and/or the second surface is arranged closer to the power supply than the first surface. The temperature sensor is mounted on the second surface.
