To provide a hair dryer equipped with a blowing-out nozzle which can effectively converge or effectively diffuse drying air being fed out from the blowing-out port of the dryer body.

The blowing-out nozzle 11 is constituted of an internal nozzle 21 and an external nozzle 22 in a double cylindrical shape. At each nozzle opening on the front side of the internal nozzle 21 and the external nozzle 22, a plurality of mountain-form converging pieces 24 and 32 are formed into the shape of a circumference. The external nozzle 22 is freely rotatably supported by the internal nozzle 21. The configuration of the blowing-out nozzle 11 is switched between a diffusing posture and a converging posture by rotating the external nozzle 22. Under the diffusing posture, the converging piece 24 of the internal nozzle 21 and the converging piece 32 of the external nozzle 22 are stacked on the inside and the outside. Under the converging posture, the converging piece 24 of the internal nozzle 21 and the converging piece 32 of the external nozzle 22 adjoin in the circumferential direction.
