PURPOSE: To provide an electric blower comprising a motor capable of improving heat radiation effect of a rotor and yoke at driving, and of insuring hold in a rotating and axis directions by a small amount of mold material without breaking magnets at a mold forming for fixing the magnets at a yoke. CONSTITUTION: The electric blower comprises the motor comprising the yoke 2 which has a circular opening at the center, formed in a substantially rectangular shape and press-fitted and supported in a frame 18; a stator 10 consisting of a plurality of arc shaped magnets 1a, 1b disposed along the inner surface of the circular opening of the yoke 2 with predetermined clearances between their ends; and the rotor 11 disposed in a space formed at the center by the magnets 1a, 1b, wherein airways 3a of air flow from a blowing fan are formed through clearances formed between the ends of the magnets 1a, 1b.
