A housing of an axial fan that allows air to flow in an axial direction includes a frame including, on an inner surface, an air channel through which air flows, stator vanes extending radially inward from the inner surface, a motor housing supported radially inward of the stator vanes, and a motor supported on one axial side of the motor housing. A portion of the stator vanes is provided on a surface on the other axial side of the motor housing.
