<p>PROBLEM TO BE SOLVED: To provide a method of inspecting a ceramic-based building material which allows easy determination of good or bad of adhesiveness between materials, in producing a ceramic-based building material by extrusion molding, and a method of producing a ceramic-based building material reduced in internal defects.SOLUTION: A method of inspecting a ceramic-based building material is for a ceramic-based building material produced by dividing a material flowing through a passage 12 within a mold 10 by a core part 11, causing the divided materials to be joined together at the downstream-side tip of the core part 11 and discharging the joined material from the mold 10 to mold. A pressure sensor 2 is provided at least in the downstream of the position where the divided materials are joined. The adhesiveness between the joined materials is inspected on the basis of a pressure value obtained by the pressure sensor 2.</p> |
