PROBLEM TO BE SOLVED: To prevent the occurrence of burr caused by the outflow of a resin to an outer periphery by uniformizing the thickness of a molded layer in the flattening molding on an optical surface for forming a braized type diffraction lattice. SOLUTION: A stamper mold, a resin material and a photoirradiator are used to perform the replica molding of a first molding support part, which has a gap enabling the outflow of the resin material between the relief pattern surface becoming the diffraction lattice and an outer peripheral part, and a second molding support part, which can suppress the outflow of the resin in the outer peripheral part, on an optical base material using the photoirradiator so that the second molding support part is slightly higher than the first molding support part by severalμm. A ring-shaped member is arranged so as to cover the first molding support part on a substrate and, especially a strong member is formed on the first molding support part by two-body constitution to impart flattening pressure.
