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 detect a temperature of the power supply; a controller; and a circuit board. The circuit board includes: a first surface; a second surface; a power supply layer in which a power supply path is formed; and a ground layer. The power supply layer and the ground layer are provided between the first surface and the second surface. The temperature sensor is mounted on the second surface, and at least one of the power supply path and the ground path is not formed in a region which overlaps the temperature sensor as viewed from a first direction, the first direction being a direction in which the first surface and the second surface are opposed to each other.
