Zusammenfassung:	A centrifugal fan introducing air via an inlet port in a direction of a rotation axis and discharging the air via an outlet port in the a direction of a centrifugal force produced by rotation includes: an impeller having a plurality of vanes around the rotation axis; and a housing including the inlet port and supporting the impeller such that the impeller is allowed to freely rotate in the housing. An inclined portion is formed at least at a part of edge portion of the inlet port, the inclined portion widening to the side that the impeller is disposed.
