PROBLEM TO BE SOLVED: To provide a mirror surface grinding method of a mold for use in the molding of an optical element capable of applying mirror surface grinding to the molding surface being the substrate of the mold without providing a pinhole or a fine pit. SOLUTION: Mirror surface grinding is applied to the molding surface 2 being the substrate of the mold 1 for molding the optical element using grindstone particles with a mean particle 6 size of 10-150 nm. The processing of the molding surface can be completed by a shape creating process for forming the shape of the molding surface of the optical element of the mold 1, a smoothing process for smoothing the molding surface and a mirror surface grinding process for grinding the molding surface using the grindstone particles with a mean particle size of 10-150 nm without applying plating treatment to the molding surface.
