PROBLEM TO BE SOLVED: To provide an optical element capable of simplifying the configuration of a die, reducing a cost required for the die, improving the yield of the optical element and securing an optical performance of the optical element, and to provide an optical element molding die for molding the optical element. SOLUTION: The optical element 21 prepared by integrally forming optical functional surfaces 2, 3 having a prescribed optical function with a holding part 6 of the same material has a protruded part 25 for position adjustment protruded toward the outside in the radial direction of the optical functional surfaces 2, 3 on an outer peripheral surface of the holding part 6 and is provided with a part 30 molded in a gate of the optical element molding die on the protruded part 25 for position adjustment.
