To provide a photo-curable resin composition for shaping an optically shaped article, which can produce, productively at a high shaping rate, solid shapes excellent in dimensional accuracy and form stability (particularly in the Z axis direction), and a method for optically shaping an article by using the photo-curable resin composition.

There are provided a photo-curable resin composition for optically shaping an article, which satisfies the formula: A1/A0≤0.95 (wherein A0 shows the transmittance of a curing light through the photo-curable resin composition, while A1 indicates the transmittance of the curing light through a photo- cured product formed by photo-curable resin composition) or the formula: B1/B0≤0.95 (wherein B0 shows the transmittance of a light having a wavelength of 355 nm through the photo-curable resin composition, while B1 indicates the transmittance of the light having a wavelength of 355 nm through a cured product formed by photo-curing the photo-curable resin composition) and a method for optically shaping an article by using the photo-curable resin composition.
