A non-combustion heating-type smoking article comprises: a mouthpiece having a suction port hole; a flavor source accommodation section that accommodates a flavor source, and that has a vapor discharge port that discharges a vapor component generated by evaporation of the flavor source; a heater for heating and evaporating the flavor source; a chamber section for establishing communication between the vapor discharge port and the suction port hole, and temporarily storing the vapor component generated by evaporation of the flavor source; and an air intake hole that establishes communication between the inside and the outside of the chamber section. The vapor discharge port is opened to only the chamber section, and during each suction, the vapor component that has accumulated in the chamber section is mixed with intake air that has flowed into the chamber section from the air intake hole and is then transported to the suction port hole.
