Abstract
An ultrasonic cleaning device () comprises: an ultrasonic oscillation plate () having a plurality of ultrasonic oscillators (); an ultrasonic wave guide chamber () for collecting an ultrasonic wave force generated by the ultrasonic oscillation plate; and a cleaning tank () in which a cleaning solution () is stored, wherein an object () to be cleaned is cleaned when it is dipped in the cleaning tank. Since an upper portion of the ultrasonic wave guide chamber is airtightly closed with the upper face () and formed into a bowl shape, an air layer () is formed between a liquid level of the cleaning solution in the ultrasonic wave guide chamber and the upper face (). The cleaning tank is joined to the ultrasonic wave guide chamber, and an ultrasonic oscillation plate is arranged so that it can be opposed to the ultrasonic wave guide chamber.
