CONSTITUTION: A liquid 2, e.g. water, to be atomized is poured in a liquid tank 1, an ultrasonic piezoelectric transducer 3 attached to the bottom of the tank 1 is vibrated by a driving circuit 7 to atomize the liquid, and the atomizedly scattered liquid is ejected through an ejection opening 5 by an air blast from a blast opening 6. Hereon, a member 7 for attenuating reflected waves made of an elastic body such as rubber or soft synthetic resin is provided at the upper part of the piezoelectric transducer 3. Ultrasonic oscillation formed by the transducer 3 and reflected on the surface of the liquid 3 is absorptively attenuated by the member 7, so as to inhibit the deterioration both of the characteristic of oscillation and the atomizability of the liquid 2 caused by the return of the ultrasonic reflected waves to the piezoelectric transducer 3.
