The present authors carried out an experimental study with a special interest upon the dynamics of the fluid in the vicinity of the boundary line of three phases ; solid-liquid-gas interface, which is so-called 'contact line.' The moving droplet on the solid substrate is accompanied with the movement of the boundary line of three phases ; solid-liquid-gas interface, which is so-called macroscopic 'contact line.' Existing studies have indicated there is a thin liquid film known as 'precursor film' ahead the contact line of the droplet. In the present study the precursor film was detected by applying conventional ellipsometer, and its existing length was evaluated as a function of a dimensionless Capillary number. The present authors also indicate the effect of tiny particle sitting on the solid surface upon the traveling droplet and precursor film dynamics.
