A theoretical study was conducted to investigate the critical condition at which the liquid droplet is rolling down on the inclined plate. The occurrence of the rolling down is controlled by the maximum width of the droplet and the critical condition can be obtained from the force balance in the tangential direction of the plate. When the droplet with a certain amount of volume is set on the horizontal plate and the plate is tilted gradually, the width can be estimated from the solution of axi-symmetric Laplace equation. On the other hand, when the volume of the droplet is increased on the plate with a fixed inclination, the width may be obtained from the condition of energy equilibrium of the system. The critical inclination angle was experimentally measured when the plate was tilted from the horizon. The results agree with those obtained in this study.
