PROBLEM TO BE SOLVED: To prepare a trial product inexpensively. SOLUTION: The trial product 1 is molded by using a molding tool which has a concavo-convex pattern 3 built detachable on a surface of a mold base 20 using a separate member from the mold base 20 and covered with a protective layer 33 over said concavo-convex pattern 3 to cover all the mold surface. A molding tool for mass production is prepared by detaching the concavo-convex pattern 3 from said molding tool, forming a concavo-convex pattern 3a similar in shape with the detached concavo-convex pattern 3 by etching or the like on the surface of mold base 20 from which the concavo-convex pattern has been detached. The products are molded by using said molding tool for mass production. COPYRIGHT: (C)2003,JPO
