PROBLEM TO BE SOLVED: To efficiently obtain a mineral plate in which a good deep rugged shape can be performed without pressing wrinkle, blurred pattern, crack or the like and which has excellent surface moldability and strength. SOLUTION: The method for manufacturing the mineral plate comprises the steps of previously mixing a calcareous stock and a siliceous stock with water, hydrothermally synthesizing the mixture, wet pressure molding a blended material containing 5 to 50 mass% of a calcium silicate hydrate having a mean particle size of 25 to 150μm, 20 to 60 mass% of a cement and 3 to 18 mass% of reinforcing fiber to form the rugged shape on at least one surface of the front and rear surface, thereby obtaining the mineral plate having a bending strength of 10 N/m<2> or more. The mineral plate is provided.
