To provide an air-conditioning apparatus that is provided with an air-sending device that includes: a housing; a fan that is disposed in the housing; a casing that guides an airflow, the casing arranged adjacent to the back side of the fan; and a stabilizer that stabilizes the circular vortex, the stabilizer arranged adjacent to the front side of the fan. Whenδ=A/D expressed by an air flow inlet port width A and a fan diameter D is 2 or lower, an outer peripheral blade inflow angleβ=δ×γradian is in the range of 0.4≧γ≧0.3. The air-conditioning apparatus provided with an air-sending device is capable of suppressing noise as well as increasing fan performance even when the inlet port is narrow.
