PROBLEM TO BE SOLVED: To provide a manufacturing device for manufacturing a high precision optical element, and a mold set for molding the optical element by suppressing temperature distribution of a molding raw material with simple constitution, in the manufacturing device of the optical element and the mold set for molding the optical element.SOLUTION: A manufacturing device of an optical element includes: a mold set 10 having a first molding tool (upper mold 11) and a second molding tool (lower mold 12) which are opposed to each other across a molding raw material 200 and a sleeve part 13 positioned at a periphery of the first molding tool (upper mold 11) and second molding tool (lower mold 12); and a plurality of stages to which the mold set 10 is transferred to heat, press, and cool the molding raw material 200. The sleeve part 13 is transferred to the stages so as to have a heat insulation part (thick part 13b-1) having higher heat insulation property than a rear side of the mold set 10 in a transfer direction (arrow D2), on a front (arrow D1) side of the mold set 10 in a transfer direction in an array direction (arrows D1, D2) of the plurality of stages so that the molding raw material 200 has small temperature distribution. |
