Summary:PROBLEM TO BE SOLVED: To improve the continuity and formation of a green sheet without lowering the concentration of slurry more than heeded and to improve uniformity in the section of the green sheet. SOLUTION: In this manufacture of an inorganic plate of cement, a slurry which is prepared by compounding reinforcing fibers with main constituents of cement and aggregate and has the slurry concentration of 15-60wt.% is filtered and dewatered and thereby the inorganic cement plate is manufactured. In this case, the vibration of a frequency 10Hz or above and an amplitude 0.1mm or above is given at an outlet of a slurry supply box or in a process of filtering and dewatering the slurry. Suction boxes 3 are disposed under a filter sheet 1 and a green sheet 4 is filtered and dewatered by suction by the suction boxes 3. The slurry supply box 5 discharges the slurry 6 from the outlet 7 thereof so that the green sheet 4 be formed on the filter sheet 1. Besides, the green sheet 4 is vibrated by vibrating a vibration plate 9 by a vibrator 8.
