Abstract (en)

The present invention restarts a controller in a stable manner. An inhaler (100) is provided with: a heater connector Cn to which a heater HTR consuming power supplied from a power source BAT to heat a rod (500) is connected; an MCU 1 configured to be capable of controlling power supply from the power source BAT to the heater HTR and including a power source terminal VDD to which power for operation is input; an LSW 4 that connects the power source BAT with the power source terminal VDD of the MCU 1; and a switch driver (7) capable of controlling opening and closing of the LSW 4. The switch driver (7) carries out a first operation of opening the LSW 4 when a restart condition is satisfied, and after carrying out the first operation, carries out a second operation of closing the LSW 4.
