Abstract
A centrifugal fan includes: a housing; an impeller which is mounted in the housing; a hub which is provided in the impeller and is rotated by a driving force of a motor; and a plurality of blades which radially extend at the hub. Each of the plurality of blades is formed to have a shape curved from a leading edge to a trailing edge in a rotational direction of the impeller in each of the plurality of blades. A farthest point from a plane connecting the leading edge and the trailing edge is defined as a peak portion. The peak portion is placed closer to the leading edge than the trailing edge.
