PROBLEM TO BE SOLVED: To provide an electric blower for excellently reducing noise, while excellently performing cooling, by coping with the problem. SOLUTION: This invention is the electric blower having an electric motor part and a blower part, and is constituted so that the electric motor part has a stator and a rotor, and the blower part has a fan, a ventilation guide member for forming a plurality of diffusers arranged for surrounding the periphery of the fan for introducing a flow of air delivered by the fan in the outer peripheral direction, and a fan casing cover for covering the fan and the ventilation guide member, and is characterized in that the stator has an inside casing supporting a stator core inside, an outside casing for internally placing the inside casing and forming a casing ventilation passage for flowing the air passed through the ventilation guide member between the outside casing and the inside casing outer periphery, and a casing exhaust passage for exhausting the air flowed in the inside casing to the outside of the outside casing by flowing in the casing ventilation passage.
