A manufacturing device provided with an inkjet head 78 for discharging a curable resin containing a liquid-repellent component and being cured by light irradiation, and an irradiation device 86 for radiating light to the discharged curable resin, wherein the irradiation dose of light to the curable resin and/or the elapsed time from discharging of the curable resin until irradiation with light is calculated so that the impact diameter of droplets of the curable resin discharged by the inkjet head is uniform. Light is radiated to the discharged curable resin in accordance with the calculated irradiation dose and/or elapsed time. The impact diameter of the curable resin can thereby be made uniform, and the shaping precision of a formed object of the curable resin can be ensured.
