摘要：<p>In an ultrasonic cleaning method, an ultrasonic wave is applied to a cleaning liquid containing dissolved gas for cleaning an object to be cleaned. The method repeats a step of continuously applying an ultrasonic wave for at least 0.2 msec and a step not applying the ultrasonic wave for at least 0.1 msec at a predetermined cycle. This prevents generation of rough and large air bubbles which inhibits transmission of an ultrasonic wave and effectively generates radical contributing to cleaning, thereby effectively cleaning the object to be cleaned.</p>
