To extend the area of a mirror and to minimize a projection part by freely detachably attaching the mirror to the side face of the main body of a hair drier.

A rectangular plane part 2b is formed on the side face of the main body barrel 2a of this hair drier 2 and a hook-and-loop fastener 3a is stuck to the plane part 2b. Then, the hook-and-loop fastener 3b to be joined with the hook-and-loop fastener 3a is stuck to the back surface of the mirror 4 and the mirror 4 is freely detachably attached by peeling off and joining the hook-and-loop fasteners 3a and 3b. Thus, since the projection part of the mirror 4 is suppressed and the mirror 4 of the large area is attached, a visual field is widened and the visibility of a rear head part is improved.
