To provide a method for manufacturing an inorganic plate by which the adhesiveness between a base layer formed from a molded body and a surface layer can be sufficiently improved by sufficiently roughening the molded body when applying a roughening treatment to the molded body, and the roughening treatment can be performed highly efficiently.
The method for manufacturing the inorganic plate includes processes of: roughening the surface of the molded body 1 formed from a ceramic-based molding material; depositing the ceramic-based molding material on the roughened face of the molded body 1 and forming a laminate 3; pressurizing the laminate 3; and curing and hardening the laminate 3. In the roughening process, the surface of the molded body 1 is dug up by protrusions 7 using a roughening roller 6 having a plurality of the columnar protrusions 7 protruded in the outer circumferential direction and carrying the molded body 1, while normally rotating the roughening roller 6 in relation to the carrying direction of the molded body 1 and setting the circumferential speed of the tips of the protrusions 7 faster than the carrying speed of the molded body 1.
