Provided is a sheet press molding method by which a molded product having a small plate thickness deviation is obtained. Such a sheet press molding method is provided with a process in which a molded product (30) having a recess and protrusion pattern portion (32), to which a recess and protrusion pattern (3) is transferred, is formed by pressurizing a sheet-shaped material (20) including 60 vol.% to 95 vol.% of a filler and a resin composition using a pair of molds (40) having the predetermined recess and protrusion pattern (3) composed of recessed portions (3a, 3b, and 3c) and protrusion portions (23a, 23b, 23c, and 23d) in at least one of a pair of the molds, in which the mold provided with a dummy pattern (24) composed of dummy protrusion portions (24a) that offset the difference between the total volume of the protrusion portions (23a, 23b, 23c, and 23d) formed on the inside (14) and the total volume of the recessed portions (3a, 3b, and 3c) disposed between the protruding portions (23a, 23b, 23c, and 23d) and the side surfaces (14b) of the inside (14) and the recessed portions (3a, 3b, and 3c) disposed between the protruding portions (23a, 23b, 23c, and 23d) on the inside (14) is used as a pair of the molds (40). |
