Abstract: A centrifugal fan includes: an impeller; and a scroll housing surrounding the impeller, the scroll housing having suction hole and discharge hole formed therein. The scroll housing includes: a base plate; a scroll wall connected to the base plate, the scroll wall being formed in a scroll shape from a cutoff; and a discharge wall extending from the scroll wall. In the centrifugal fan, a flow path extending portion having a flow path sectional area extending toward an air flow direction convexly protrudes in the outer direction of the scroll housing in the base plate. Accordingly, a flow path is formed to extend in two directions including a direction in which the scroll wall extends and a direction in which the flow path extending portion protrudes. Thus, the static pressure of a discharge air current can be quickly recovered, and the blowing performance of the centrifugal fan can be improved.
