Abstract: Disclosed is an air conditioner that suppresses generation of leakage vortices between a fan and a shroud. An air conditioner according to an embodiment of the present invention includes: an axial fan for blowing air; a shroud partially surrounding a circumference of the axial fan to guide air blown by the axial fan; and a fence ring provided in an inner surface of the shroud and protruding in a radial direction from the inner surface of the shroud. In addition, the fence ring is disposed between a downstream end of the axial fan and a downstream end of the shroud.
