A non-burning type flavor inhaler includes a control unit that controls power supplied from a power source to an atomizer. The control unit controls, in one puff action in a standard mode, controls the power source to supply standard power amount to the atomizer in a duration before a first duration elapses. The control unit, in one puff action in the reduced mode, controls 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 controls 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.
