Keywords:needle-free injector, micro-bubble, shock wave

In this study, as a development of a needle-free injector, we make a structure for shooting out micro-bubbles and propose a injection system that uses collapse phenomena of micro-bubble. In this time, we measured the pressure of collapse of micro-bubble and visualized shock wave which is generated in a moment when the micro-bubble collapse by using schlieren method.
