Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an inorganic board made by a paper-making process which shows excellence in workability, flexibility, strength, a screw holding force and the like, and has high shock resistance and moisture release and absorption required for a moisture-conditioning building material in spite of no use of asbestos as a raw material, and to provide its manufacturing method. SOLUTION: The manufacturing method of the inorganic board made by the paper-making process comprises the steps of wet-mixing a compound to obtain slurry, the compound containing 20 to 60 mass% of a matrix-forming hydraulic material, 1 to 50 mass% of an inorganic filler, 3.5 to 12 mass% of a reinforcing fiber (excluding asbestos) and 10 to 50 mass% of calcium silicate hydrate obtained by beforehand carrying out hydrothermal synthesis of a calcareous material and a siliceous material, subjecting the slurry to the paper-making process to obtain a green board, dehydrating the obtained green board under pressure, then curing and hardening it. The calcium silicate hydrate having a special particle diameter and the specific reinforcing fiber are used, and special conditions in the paper making process are employed.
