To facilitate the adjusting work while the atomizing angle can be adjusted with excellent accuracy.

A laser pointer 20 consists of a body 22 in which a fitting hole 21 to be fitted to the atomizing nozzle 11 of an atomizer 3, a laser beam oscillator 23 incorporated on the tip of the body 22, and a power source (dry battery) 24 incorporated on the body 22. The laser beam oscillator 23 is coaxially arranged with the fitting hole 21 (i.e., the atomizing nozzle 11), and the optical axis of the laser beam BL approximately agrees with the atomizing axis LI of the atomizer 3. A switch 25 is provided on the body 22, and the laser beam BL is outputted by operating the switch 25 by an operator. The operator holds only the laser pointer 20 in adjusting the angle of the atomizer 3 and integratedly oscillates the laser pointer 20 and the atomizer 3 with each other.
