Abstract
In a centrifugal fan, a tangent line, which is tangent to a positive pressure surface of a blade and passes through a trailing edge of the blade, is defined as a first tangent line. A virtual circle is centered on a rotational axis and passes through the trailing edge. A tangent line, which is tangent to the virtual circle and passes through the trailing edge, is defined as a second tangent line. An angle, which is placed in front of the first tangent line in a rotational direction and is on an outer side of the virtual circle relative to the second tangent line, is defined as an outlet angle. When a change in the outlet angle is viewed at each of a plurality of locations along the trailing edge, the trailing edge has at least one inflection point.
