There is provided an optical modeling apparatus (1) that forms a model of a desired shape by sequentially forming hardened layers by irradiating a light-curable resin with light. The apparatus includes a first light source (11) that emits a light beam for plotting on the resin, a scanning device (21,22) that scans the light beam from the first light source over the resin, a second light source (31) that emits light that irradiates one fixed region of the resin at a time, and a spatial light modulator (32) that spatially modulates the light from the second light source (33) to blanket-expose a specified region of the resin. The light beam from the scanning device (21,22) and the light from the spatial light modulator (32) form each hardened layer.
