In order to clarify the process of the mechanical effect caused by micro-bubbles, detailed behaviors of a single bubble adhered to solid surface were optically observed using an ultra high-speed camera. The changing pressure from the bubble to the surface was simultaneously observed by a thin piezoelectric transducer. At the time of collpse, we confirmed the radiation of a micro-jet from the bubble, which was followed by a counter-jet. An impulsive positive pressure to the surface was also observed synchronously with the collapse motion. This pressure seems to come from the jet flow or the violent vibration of the bubble.
