To provide a high-quality optical article having an optical element such as a minute fresnel lens, a lenticular lens, a microlens array or a prism lens shape.
The manufacturing process of the optical article comprises: a step 101 of applying a radiation curing resin solution 20 on a planar mold 1; a step 102 of leveling to smooth the resin solution using a translucent substrate film 15 larger than the planar mold; a step 103 of squeezing with a pressure roll 6 from the opposite side of the application side of the resin solution of the translucent substrate film, leveling the resin solution on the translucent substrate film and sucking the resin solution extruded from the mold while smoothing; a step 104 of irradiating radiation from the opposite side of the application side of the resin solution of the translucent substrate film by radiation irradiation means 8 to harden the resin solution on the translucent substrate film; and a step 105 of removing a cured product 20 of the resin solution along with the translucent substrate film from the planar mold.
