PROBLEM TO BE SOLVED: To provide a motor driven blower in which a motor efficiency can be improved while suppressing effectively the temperature rise of a stator in a frame. SOLUTION: The motor driven blower 3, in which a wind discharging part 34 is provided at the fan cover mounting part 22b bulged from the metal tubular part 22a of the frame 22 of a motor section 3a, the part of the wind discharged from the fan of the blower section 3b is circulated through a wind discharging part 34 and discharged to the outside of the metal tubular part 22a, and the residual wind is circulated to the inside of the frame 22, is premised. A heat sink fin 35, to which the heat of the stator is transferred, is louvered to the tubular part 22a of the frame 22 in which the stator and the rotor are disposed in the interior, and this heat sink fin 35 is exposed with the wind discharged from the wind discharging part 34.
