PROBLEM TO BE SOLVED: To provide a manufacturing method for a calcium silicate molded product reduced in equipment investment, enhanced in productivity as compared with a conventional method, in manufacturing the calcium silicate molded product by press dehydration molding. SOLUTION: In the manufacturing method of the calcium silicate molded product having a press dehydration molding process of an aqueous slurry containing calcium silicate, the press dehydration molding process comprises a preforming process (1) for applying press dehydration molding to the aqueous slurry containing calcium silicate by a preforming apparatus until a shape retainable preform is obtained and a main molding process (2) for subjecting the obtained preform to press dehydration molding by a main molding machine until a predetermined molded product is obtained.
