PROBLEM TO BE SOLVED: To improve the product quality and productivity of a molding by a method wherein the releasability of the molding from a molding surface is improved. SOLUTION: Molding surfaces 11a, 12a, 13a and 14a, with which a desired molding 1 is molded, are made of ceramic material. By making the most of the mechanical characteristics such as the chemical resistance, solid lubricity and the like of the ceramic material, the releasability of a molding 1 from the molding surfaces 11a, 12a, 13a and 14a is improved. |
