Abstract
An ultrasonic generator that includes an ultrasonic generating element and a first acoustic path. The ultrasonic generating element includes a frame including a through hole in its central portion, a first transducer being flat-shaped and bonded to a first principal surface of the frame, and a second transducer being flat-shaped and bonded to a second principal surface of the frame and is configured to generate ultrasonic waves in a buckling tuning-fork vibration mode where the first transducer and the second transducer vibrate in mutually opposite phases. The first acoustic path is disposed so as to be adjacent to at least one of both principal surfaces of the ultrasonic generating element and configured to compress the ultrasonic waves generated from the ultrasonic generating element and to allow the ultrasonic waves to propagate therethrough in a direction along the principal surface of the ultrasonic generating element.
