The invention provides an electric blower which makes compatible the miniaturization by application of an axial blower and efficientization according a wing tip vortex to inhibition is provided. In anelectric blower which it has, an electric motor, the axis of rotation of an electric motor and an axial blower of a same axis, and a fan casing that has a suction opening while covering an axial blower, a moving blade of an axial blower which has wings of two or more sheets, and a ring in which at least a part of end of wings is abutted, and a fan casing has a level difference part in an inner cylinder surface, and the electric motor side largely an inner diameter of a fan casing compared with the suction opening side, at least one copy of a ring. An electric blower which is placed at the electric motor side rather than a level difference part of a fan casing, and is characterized by an outer diameter of a ring being smaller than an inner diameter on the electric motor side of a fan casing more largely than an in
