The surface acoustic wave (SAW) radiates the longitudinal wave, when the SAW propagates at liquid/solid interface. The radiated SAW propagates in the droplet and is converted to the SAW. Therefore, it is possible to obtain the longitudinal wave velocity of the droplet by observing the SAW. In this paper, we demonstrated to determine the longitudinal wave velocity from the observed values. The results indicate that the new measurement method of the longitudinal wave velocity is realized with the SAW device and small droplet.
