PROBLEM TO BE SOLVED: To provide an electric blower improved in pressure recovery in an air guide, and having a reduced loss at a flow changing part and improved air-blowing efficiency. SOLUTION: A plurality of stationary blades 11 of the air guide 7 are each composed of two stationary blades of a first blade 20 and a second blade 21 at their peripheral ends, to provide the electric blower which can prevent sudden enlargement in the sectional area of a flow path while leading an air flow downward (in a direction of a return passage), improves pressure recovery in a diffuser passage, reduces a loss at the flow change part and enhances the air-blowing efficiency.
