PROBLEM TO BE SOLVED: To form a clear embossed pattern having a feel of deep carving on the surface of an inorganic board. SOLUTION: A slurry containing hydraulic inorganic powder and wood pulp is fed to a paper-making machine to form a sheet mat, and a plurality of sheet mats are stacked one upon another to form a laminated mat which has a proper thickness. Under the condition that the moisture content of the laminated mats is 70-100 wt.%, a mold plate, on which an embossed pattern is formed, is pressed against the surface of the mat under pressure of 15 MPa ot more and then the mat is cured and solidified, whereby a corner 4 or a curved portion of the mat can be prevented from cracking.
