To easily form a predetermined mold pattern to the surface of a member for a mold with high precision without requiring much processing time.
The manufacturing method of the mold 10 for the optical part includes a process for forming a photosensitive material layer 12 on the surface of the member 11 for the mold, a process for exposing the photosensitive material layer 12 to the shape of the predetermined mold pattern 13, a process for developing the exposed photosensitive material layer 12 to form the predetermined mold pattern 13, a process for forming a protective layer 14 on the surface of the developed photosensitive material layer 12, a process for melting the photosensitive material layer 12 having the protective layer 14 formed to the surface thereof, a process for filling the space 15 formed by melting the photosensitive material layer 12 with a highly rigid material and a process for curing the filled highly rigid material to form a highly rigid material layer 16.
