Abstract

An ultrasonic cleaner includes: a cleaning tank having a recess that enables insertion of a dispensing nozzle to be cleaned; and an ultrasonic transducer having a piezoelectric element and a front mass, in which a lateral surface portion of the cleaning tank is provided with a through-hole having an opening on an outer wall surface of the cleaning tank and an inner wall surface of the recess, the front mass is inserted into the through-hole, and a tip portion of the front mass is disposed so as to emit ultrasonic waves from the side of the dispensing nozzle. Thus, it is possible to provide an ultrasonic cleaner that has a configuration suitable for mounting in a narrow space such as a conveyance rack, that generates small liquid-surface fluctuations, and that is capable of using strong ultrasonic waves to irradiate an outer peripheral portion of a nozzle.
