PROBLEM TO BE SOLVED: To provide an electric blower capable of reducing the number of components, the size of shaft length of an electric motor part, the size of a cleaner main body and cost. SOLUTION: This electric blower is provided with the electric motor part 6 in which a drive part 3 comprising a stator 1 and a rotor 2 is covered with a bracket 4 and a frame 5, and with a blower part 11 in which a blast fan 8 mounted to a rotational shaft 7 of the rotor 2 is covered with a fan cover 10. The electric blower is further provided with a cooling fan 21 mounted to the rotational shaft 7 of the rotor 2 and cooling the drive part 3. The cooling fan 21 is built in the electric motor part 6, and is arranged and contacted between a bearing 13 rotatably supporting the rotational shaft 7 of the rotor 2 and a snap ring 22 stopping the bearing 13.
