PROBLEM TO BE SOLVED: To provide an optical shaping apparatus capable of performing optical shaping of high precision at a high speed. SOLUTION: The optical shaping apparatus 1 for forming a shaped article having a desired shape by successively forming a cured layer by irradiating a photosetting resin with light is equipped with a first light source 11 for emitting a light beam for performing drawing on the photosetting resin 2, a scanning means 12 for scanning the light beam radiated from a first light source 11 on the photosetting resin 2, a second light source 31 for emitting the light applied on the photosetting resin 2 at every specific region, and a spatial light modulation means 32 for spatially modulating the light emitted from the second light source 31 to collectively expose the predetermined region on the photosetting resin 2. The spatial light modulation means 32 is a reflection type spatial light modulation means and each of the cured layers of a shaped article are formed by the light beam scanned by the scanning means 12 and the light spatially modulated by the spatial light modulation means 32.
