PROBLEM TO BE SOLVED: To provide an optical glass element shaping mold which exhibits a good release property between glass and the shaping mold even in repeated molding of phosphate glass or the like having strong reactivity and a high softening point, high adhesion strength between each of various optical glass element shaping mold base materials and a coating layer, excellent durability and suppressed of degradation and discoloration of the coating layer. SOLUTION: A coating layer containing 1-10 wt.% molybdenum (Mo), 10-30 wt.% rhenium (Re), 1-15 wt.% Rhodium (Rh) and/or ruthenium (Ru), 40-85 wt.% iridium (Ir) and platinum (Pt) and 0-5 wt.% gold (Au) is laminated on the optical glass element forming surface of the optical glass element shaping mold base material.
