To provide a method for manufacturing a cement plate, which effectively prevents a hardening material supplied into a hollow hole from outflowing.
The method for manufacturing a cement plate 1 includes the steps of: extrusion molding a hydraulic material 2 so as to form a molded object 4 having a hollow hole 3; supplying a hardening material 5 having flowability into the hollow hole 3; cutting the molded object 4 in the direction crossing the extrusion direction X of the molded object 4 in a state that the hardening material 5 is arranged in the hollow hole 3 such that the end of the molded object 4 is deformed to have a reduced opening area of the hollow hole 3 at the section plane of the molded object 4; and curing and hardening the molded object 4.
