PCT No. PCT/JP96/00350 Sec. 371 Date Nov. 6, 1996 Sec. 102(e) Date Nov. 6, 1996 PCT Filed Feb. 16, 1996 PCT Pub. No. WO96/25677 PCT Pub. Date Aug. 22, 1996The surface and/or interface of a lens or the like is formed with a convex-microgranular surface. For this purpose, a stamper 108 having a concave-micro-granular transfer-molding surface transfer-molded from a convex-microgranular surface comprised of SiO2 or the like and varying continuously in the index of refraction is used to reproduce the convex-microgranular surface.
