Disclosed is a large-sized ceramic plate obtained by an extrusion molding method wherein the warpage of the plate is suppressed, and thus, a texture can be formed thereon without a grinding work after baking. Provided is a large-sized ceramic plate characterized in that a glaze layer is formed on the surface of a ceramic substrate in accordance with need; the warpage of the ceramic substrate is 1.5 mm or less; and the ceramic substrate is obtained by extrusion molding a ceramic raw material added with a needle-shaped crystallized mineral to produce a cylindrical molded body, cutting and opening the cylindrical molded body to spread out in the form of a plate, rolling the plate with a flattening roller to form a raw molded body, and thereafter, baking the raw molded body.
