PROBLEM TO BE SOLVED: To enable a formation of a stereo lithography having a stable laminating pitch and good quality by uniformly coating an uncured resin on a curd resin layer in the lithography, and eliminating a defect of the uncured resin film even in a stereo lithographic product having a large laminate sectional area. SOLUTION: A blade section (201) of the squeegee device for the stereo lithography has a doctor blade (21a) formed of a urethane resin, and an extended plate (18) in which the blade (21a) is extended under tension. The blade (21a) is formed in a V shape at its inside surface toward an advancing direction. The blade (21a) scrapes the uncured resin on the cured resin layer (17) and advance while uniformly coating, while scraping and gathering (4g) the uncured resin to a substantially center (c) on the layer (17) tending to lack the uncured resin by the V-shape-like shape.
