PROBLEM TO BE SOLVED: To restrict loss of circulating currents generated due to leak of air currents in an inducer, and improve suction ability in an electric blower. SOLUTION: This blower is provided with a pair of a front surface shroud 111 and a rear surface shroud 112, a plurality of resin inducers 115 having three-dimensional curved surfaces provided in the shrouds, a plurality of sheet metal blades 116 jointed with the inducers 115, a hub 114 provided inside the inducers 115, a plurality of grooves 119 provided in the front surface shroud 111, and engagement parts 120 on the inducers 115 to be engaged with the grooves. Deterioration of air output caused by circulating currents generated due to leak of the air currents at the inducers 115 is thus restricted, thereby suction ability is improved.
