The present invention relates to a centrifugal fan. The centrifugal fan according to one aspect comprises: an impeller for suctioning or discharging air; a motor for rotating the impeller; a housing accommodating the impeller, and having an inlet through which the air is suctioned and an outlet through which the air is discharged by the rotation of the impeller; and a cutoff part formed at one side of the outlet, wherein a flow cross-sectional area of the air flowing inside the housing gradually increases from the cutoff part toward the outlet along a flow direction of the air, and the distance in the rotary axis direction of the impeller from the bottom surface part of the impeller to the inner circumferential surface of the housing increases gradually, at least partially, from the cutoff part toward the outlet along the flow direction of the air. |
