PROBLEM TO BE SOLVED: To provide a composite optical element with less internal stress and no sink by reducing thickness deviation in a resin layer. SOLUTION: This method for manufacturing the composite optical element comprises a first discharging step of discharging a first ultraviolet curable resin 11 to a substrate lens, a first irradiation step of irradiating and curing ultraviolet rays 200 to the first ultraviolet curable resin 11, a second discharging step of further discharging a second ultraviolet curable resin 12 on the surface of the cured first ultraviolet curable resin 11, an enlarging step of approximating a mold 15 to the second ultraviolet curable resin 12 and expanding this, and a second irradiation step of irradiating and curing the ultraviolet rays 200 to the expanded second ultraviolet curable resin 12. The first irradiation step is performed while the substrate lens with the first ultraviolet curable resin 11 discharged thereto is rotated at a prescribed circumferential speed.
