PROBLEM TO BE SOLVED: To provide a mold capable of easily forming a predetermined uneven pattern to the surface of the mold for molding a synthetic resin in a short time at a low cost and capable of easily manufacturing a plurality of synthetic resin products same in shape and quality. SOLUTION: A pattern is formed on a thin substrate 11 made of a metal or a synthetic resin by a large number of dot holes 3 or/and linear holes to obtain the mold 10 for the synthetic resin product. A substrate obliquely changed in thickness may be used. The wall surfaces of the dot holes or linear holes may be formed as inclined surfaces of about 45 deg. with respect to the surface of the substrate. |
