A non-burning type flavor inhaler having a shape extending from a non-inhalation end toward an inhalation end along a predetermined direction, comprising: an aerosol source configured to generate an aerosol; an atomizer configured to atomize the aerosol source without burning; a power source configured to supply power to the atomizer; and a control unit configured to control a power amount supplied from the power source to the atomizer, characterized in that the control unit is configured to selectively perform a standard mode to be applied to a user whose required time for one puff action for inhaling the aerosol is within a standard required time duration, and a reduced mode to be applied to a user whose required time for one puff action for inhaling the aerosol is shorter than the standard required time duration, the control unit, in one puff action in the standard mode, being configured to control the power source to supply standard power amount to the atomizer in a duration before a first duration elapses, and to control the power source to supply power smaller than the standard power amount to the atomizer in a duration after the first duration elapses, and the control unit, in one puff action in the reduced mode, being configured to control the power source to supply first power amount greater than the standard power amount to the atomizer in a duration before a second duration elapses, and to control the power source to supply second power amount smaller than the first power amount to the atomizer in a duration after the second duration elapses and before a third duration elapses, and to control the power source to supply power smaller than the second power amount to the atomizer in a duration after the third duration elapses. an aerosol source configured to generate an aerosol; an atomizer configured to atomize the aerosol source without burning; a power source configured to supply power to the atomizer; and a control unit configured to control a power amount supplied from the power source to the atomizer, characterized in that the control unit is configured to selectively perform a standard mode to be applied to a user whose required time for one puff action for inhaling the aerosol is within a standard required time duration, and a reduced mode to be applied to a user whose required time for one puff action for inhaling the aerosol is shorter than the standard required time duration, the control unit, in one puff action in the standard mode, being configured to control the power source to supply standard power amount to the atomizer in a duration before a first duration elapses, and to control the power source to supply power smaller than the standard power amount to the atomizer in a duration after the first duration elapses, and the control unit, in one puff action in the reduced mode, being configured to control the power source to supply first power amount greater than the standard power amount to the atomizer in a duration before a second duration elapses, and to control the power source to supply second power amount smaller than the first power amount to the atomizer in a duration after the second duration elapses and before a third duration elapses, and to control the power source to supply power smaller than the second power amount to the atomizer in a duration after the third duration elapses.
