Abstract
An air blower including a convex part protruding away from the rotation axis of an impeller. When arbitrary cross-sectional surfaces are provided by cutting the convex part in a parallel direction with the rotation axis, each point of the inner circumferential surface of the convex part, which has a maximum distance from the rotation axis, leans toward a first plate of the first and second plates, at which inlets are formed.
