To provide a low-noise electric blower with high blast efficiency by achieving multi-blade of an inducer, and to provide an electric vacuum cleaner using the same.
The inducer 125 is formed of two parts of an inducer A125a and an inducer B125b, and engagement parts 143a, 143b are arranged respectively in blade parts 127a, 127b. A hub part A126a is inserted in the outer periphery of a hub part B126b, and the inducer B125b is fixed in a rotary shaft 107 of the electric blower 101 from above the hub part B126b by a fastener 112, thereby connecting the blade parts in the engagement parts 143a, 143b. This structure can prevent the fastening force of the fastener 112 from being applied only to the inducer A125a. Therefore, the inducer A125a can be thinned, and thus, multi-blade of the resin inducer 125 mass-manufacturable with a plain die structure can be achieved.
