A non-combustion type flavor inhaler (100) comprises: a housing/outer wall (124) having an airflow path (122) continuing from an inlet/air introduction hole (125) to an outlet/a suction hole (141); an atomizing part/heat source (80) that atomizes an aerosol source without burning; a sensor (20) outputting a value that changes according to a user's puff operation; and a heat source control unit (53) that controls a power supply output to the atomizing part (80) based on an absolute value of slope formed by two or more response values derived from a value output from the sensor (20) such that an aerosol amount falls within a desired range, wherein the aerosol amount is an amount of an aerosol to be atomized by the atomizing part (80) in one energization to the atomizing part (80).
