摘要：
PROBLEM TO BE SOLVED: To provide a lightweight ceiling board having a sufficient bending strength, incombustibility, sound absorbing performance, thermal insulation, adequate radio wave absorbing property with good design and appearance in addition to radio wave shielding property. SOLUTION: Ceiling boards obtained by wet type paper production using water dispersion slurry of the mixture of rock wool, beat pulp, binder, coagulator, natural mineral fibers and carbon fibers blended in a specific range; laminated, constituted ceiling boards of the mixture having a layer not blended by the carbon fibers; ceiling boards adhered with a metal foil; and also ceiling boards blended with an organic-based paint coated with an amount greater than that of the blended amount to the ceiling board are used for solving the problem.
