Abstract
An impeller of a blower is disposed with circular support plates that are made of a resin and rotate about an axis of rotation and a plurality of blades that are made of a resin. The blades are disposed on outer peripheral portions of the circular support plates so as to be parallel to an axis of rotation, and serrated shapes are formed on the blades by cutting out blade tips at plural places. Additionally, a step is formed in a blade face of each of the blades at a position a predetermined distance from the blade tip where the serrated shape is formed.
