PROBLEM TO BE SOLVED: To provide an optical element manufacturing method to reduce production cost.SOLUTION: The optical element manufacturing method to form, by curing resin material, a DOE molding section stacked on a glass substrate comprises supplying the resin material which is molding material to the surface of the glass substrate formed almost in a disk shape, spreading the resin material by bringing a mold 50 to the surface of the resin-supplied glass substrate, and curing the spread resin material. In the mold 50, a groove section 52 with a pair of wall surfaces of V-shaped cross-section is extending like a circular ring in a facing surface section 53 facing the periphery vicinity of the glass substrate. |
