[Problem] The object lies in providing a photo-curable resin composition for three-dimensional molding which does not require a support material, and which can be cured by means of light irradiation while being extruded from a nozzle through a simple FDM method to be stacked and molded in a short period of time.[Solution] A photo-curable resin composition having a viscosity at 20 °C of 0.2 Pa·s or more and a viscosity at 150 °C of 1000 Pa·s or less was found.
