PROBLEM TO BE SOLVED: To provide a hydraulic formed body in which cost occupied by reinforcing fiber can be made lower in a manufactured sheet as a building material particularly useful as a substitute for asbestos while sufficiently securing its reinforcing properties. SOLUTION: The hydraulic formed body comprises reinforcing fiber consisting of mixed fiber between an organic fiber group A and an organic fiber group B, and in which, as for affinity to cement, the organic fiber group A>the organic fiber group B is satisfied, also, the fiber mixing ratio between the organic fiber group A and the organic fiber group B in the mixed fiber satisfies 70/30 to 10/90, and the average fiber strength of the mixed fiber obtained by following expression is≥6.5cN/dtex: <<the average fiber strength>>=<<the fiber strength of the A group>>×X+<<the fiber strength of the B group>>×Y, wherein, X is the fiber mixing ratio of the organic fiber group A; Y is the fiber mixing ratio of the organic fiber group B; and X+Y=1 is satisfied.
