PROBLEM TO BE SOLVED: To reduce the raw material loss and at the same time, make it possible to continuously manufacture a good molding without investing equipment cost by forming a part for receiving both side edge parts of a water-permeable sheet on the suction face of a suction means, of a waterpermeable member which is made of a raw material whose solid component is non-penetrable and communicates with a suction device. SOLUTION: The suction box 6 of a suction means 4 is equipped with a box body 6a and a water-permeable member 6b. On the suction face 62 side of the box body 6a, both edge parts 8 are notched by the thickness of the water- permeable member 6b from the center part 67 and a plurality of suction holes 63, 63' are pierced. The water-permeable member 6b is formed of the same material as a water-permeable sheet 2. In addition, leak barrier walls 66a, 66b are formed on both sides of the suction face 62 and an air hole 64 communicating with a decompression box 5 is formed on the bottom face side. Even when a molding raw material leaks from the edge of the water-permeable sheet 2, passage of the solid component is not allowed by providing the water- permeable member 6b and thus it is possible to prevent the raw material loss and air leakage into a vacuum from occurring.
