PROBLEM TO BE SOLVED: To obtain an interior finish plate for building which is fitted to the ceiling, wall, and floor of a closed habitable space, adsorbs/decomposes/ eliminates gaseous evaporated chemicals and odors, absorbs excess moisture, prevents the propagation of floating bacteria and molds, and maintains a safe, comfortable, hygienic habitable space over a long period. SOLUTION: A zeolite mineral which comprises crystalline zeolite and volcanic vitreous materials and has water resistance to prevent collapse by moisture absorption/water absorption, a specific surface area of at least 15 m/g, a base substitution capacity of meq/100 g and Mohs hardness of 4.8-5.8 is cut directly by a diamond particle blade having diamond particles 0.5-2.0 mm in diameter into pieces having at least 3 mm thickness and a required area to make a zeolite plate 3, which is dried to be 3.0% or below in water content. A coating layer coated with a binder made of cement, gypsum, diatomaceous earth, or clay containing substantially at least 0.1 wt.% of electromagnetic wave radiation ceramic fine powder which can excite water molecules is formed at least on one side of the plate.
