Deodorizing ability of a diatomaceous material mined from Wakkanai district in Hokkaido Pref. was examined in detail. This material is widely distributed in the market as a material of environmentally-friendly inner-wallboard. Alternative introductions of a model odor {NH_3, CH_3CHO, or (CH_3)_2S} mixed-N_2 gas flow and a pure N_2 gas flow into the diatomaceous material showed reversible adsorption and desorption of the odor components at 25℃, reconfirming regeneration of deodorizing ability for the diatomaceous-wallboard by ventilation of rooms with these wallboards. The adsorbed quantities of the odors onto the diatomaceous material during one hour readily cleared the odor level 3: 2.3 ppm for NH_3, 0.14 ppm for CH_3CHO, and 0.044 ppm for (CH_3)_2S, respectively.
