Zusammenfassung:	Slim-profile centrifugal fan made up of a housing, a motor component, and a airflow-generating component. A disk portion, a cylindrical portion, a plurality of posts, and a plurality of blades compose the airflow-generating component. The plurality of posts project from, and are arranged at a predetermined circumferential spacing along, the outer circumferential surface of the cylindrical portion; and each of the plurality of blades is provided on a respective one of the posts. The posts are of sufficiently greater thickness than the blades. Accordingly, air spaces are formed in between the posts and the blades, yet the blades are retained firmly on the cylindrical portion by the posts.
