Abstract
An ultrasonic generator that is capable of increasing output sound pressure is provided. An ultrasonic generating element is accommodated in an accommodation space that is formed by a first case member and a second case member. The ultrasonic generating element is secured to the first case member via a plurality of first supporting members. The first supporting members are provided so that, in a first acoustic path that includes a space formed between a bottom surface of the ultrasonic generating element and a top surface of the first case member and that extends to sound-wave emission holes, a transverse section of the acoustic path has a portion that becomes smaller than another portion thereof.
