PROBLEM TO BE SOLVED: To simply shape an object three-dimensionally with high dimensional precision and high productivity by bringing the lower face of a light-transmitting film into contact with the liquid face of a photocurable resin liquid and pressing the resin liquid to be flattened, and then forming a cured resin layer with a specified pattern and a specified thickness through the emission of light from above and further, peeling the film to again form a photocurable resin liquid layer with a specified thickness on the curable resin layer. SOLUTION: The entire curable resin layer L1 on the liquid level 2' of a photocurable resin liquid 2 in a shaping bath 1 is covered with a continuous long light-transmitting film 4 using supply rollers 5a, 5b and take-up rollers 6a, 6b. The lower face of the film 4 is brought into contact with the liquid level 2', which is, in turn, pressed using a light-transmitting pressing plate 8 to be flattened. Further, light is emitted to the resin liquid 2 from a light source 9 above so that the resin liquid 2 is photocured to the specified pattern and thickness and a cured resin layer L2 is formed on the lower face of the film 4. In addition, a pressing plate 8 is sidetracked to gradually peel the film 4 from the cured resin layer L2 and a table 3 on which the cured resin laminates L2/L1 are placed is lowered to repeat the process. Thus it is possible to manufacture an optical three-dimensionally shaped object with a flat surface and a high dimensional precision rapidly, efficiently and smoothly.
