PROBLEM TO BE SOLVED: To provide a method for producing a hydraulic inorganic molding which can produce the molding of stable quality even when the molding is formed in an plate shape, needless to say, and in an uneven shape such as corrugation. SOLUTION: A cylindrical hopper 9 in which a notch is formed in the lower end part of a wall 91 on the advance direction side of a water-permeable sheet 2 is arranged to make the lower end surfaces of walls 92, 93 other than a notch forming part contact the terminal fringe parts of the sheet 2 and/or a suction means 4 so that the notch forming part faces the initial end part of a vacuum- dewatering area V, and a clearance whose shape is almost the same with the cross-sectional shape of a molding to be obtained and which is thinner than the cross-sectional shape is formed by the notch and the sheet 2. A molding raw material 8 packed in the hopper 9, after being pre-supplied continuously from the clearance on the sheet 2 in a clearance shape, is developed/molded by development rolls 33, 33 while being supplied further from a raw material supplying apparatus 3.
