In contact line with gas dissolution, the Marangoni flow that originates in the concentration difference appears. More intense flow is generated when the relative movement etc. of the solid phase to the liquid phase act in this area. At this time, a capillary force is caused for the solid surface. In this research, we detected a capillary force and concentration change in the limited part in the contact line with gas dissolution. And, the result that the concentration rise is promoted by the relative movement of the solid phase was obtained. Moreover, it is suggested that there be correlations in a concentration and a tangential force change.
