The authors have studied about a liquid atomization by the impinging of two jets. In this paper, the film formation by jets with low velocity is treated. The relations between the properties of jets, i. e. the velocity, the impinging angle, the thickness and velocity distributions on a film, the size and the shape, are made clear by the experiments and compared with the calculated results. A particle track method for the velocity measurement, an interference method for the thickness measurement and a microflushed photograph for the size and shape of film have been used. By considering that the disintegration is caused by the relation between inertia force and surface tension at the edge of film, the size of film at the surface angle α is expressed as R_α=1/2 p/σ V_<1α>^2 K_α sin^2δ_α The velocity distribution of jet has influences on the formed film. The minimum thickness at the same surface angle is proportional to the surface tension and inversely so to the density and the square of velocity of the film.
