PROBLEM TO BE SOLVED: To provide a cooling structure of air blower, which comprises a motor for rotating a fan and a drive circuit substrate for driving the motor and is capable of cooling a radiation member for cooling a circuit element on the substrate by applying wind generated by the rotation of the fan, and prevent water from adhering to the drive circuit substrate, while restraining costs. SOLUTION: The air blower 1 comprises air passages such as a diversion duct 19b and an air blow path 18a, which performs blowing operation by rotating a fan 16 with a motor 3, cool the inside of the motor 3 by introducing a part of wind generated by the rotation of the fan 16 as cooling wind into the inside of the motor 3, and discharges the wind to the outside of the motor 3. The drive circuit substrate for driving the motor 3 is arranged at a prescribed position except for the air passages, and the radiation plate 24, which is abutted against the circuit element of the substrate which is to be cooled is exposed in the air passages.
