    • PROBLEM TO BE SOLVED: To provide a method for manufacturing a cement-based sheet, capable of being formed to be ultrathin and excellent in high class feeling, stateliness, and shininess. SOLUTION: The method for manufacturing the cement-based sheet includes: the kneading step of obtaining a compound 2 by kneading (A) cement, (B) fine powders having BET specific surface area of 5-25 m 2 /g, (C) a fine aggregate, (D) a water reducing agent, (E) metal fiber, and (F) water; a molding step which casts the compound 2 obtained in the kneading step in a formwork 1 where a material for forming at least a bottom surface is glass or synthetic resin, and performs a molding of the compound 2 by closely attaching the compound 2 cast in the formwork 1 with a face-down formwork 3 having nonwoven fabric 3a so that the nonwoven fabric 3a opposes to the compound 2; the curing step which cures the compound 2 in such a state that the compound 2 in the formwork 1 and the face-down formwork 3 are closely attached, and obtains a hardened body of the compound 2; and the demolding step which obtains the cement-based sheet 4 having a shiny surface 4a by demolding the hardened body of the compound 2 from the formwork 1.
