A non-combustion-type flavor inhaler includes: an atomization assembly including an atomizer configured to atomize an aerosol source without combustion; and a power supply assembly including a power supply for supplying power to the atomizer. The power supply assembly includes: paired electrodes for electrical connection with the atomizer; and a first electrode and a second electrode electrically connected with the power supply. At least one of the first electrode and the second electrode is electrically connectable to a charger for charging the power supply. The non-combustion-type flavor inhaler is provided with a control circuit configured to detect a predetermined current in an opposite direction to a direction of a current flowing through the first electrode or the second electrode when the charger charges the power supply.
