An inorganic sintered body containing ocher, diatomite and feldspar is provided to obtain a firm disinfectant object of deodorization that generates far-infrared ray and anions for activating living body and plant. An inorganic sintered body is manufactured by a process comprising: making a mixture composition comprising 80-120 parts by weight of ocher, 50-80 parts by weight of sintered diatomite and 30-50 parts by weight of feldspar; adding 5-15wt% of water to the mixture and kneading the mixture; putting the kneaded mixture into an extruder for removing air bubble and forming an inorganic object by pressing the mixture in a mold having desired size and shape; treating the inorganic object at 800deg.C for 1-3 hours as primary heat-treatment; treating the inorganic object at 1,600deg.C for 1-3 hours as secondary heat-treatment; and polishing the inorganic object to have a shape of medal. The inorganic sintered body optionally contains at least one additive selected from a group consisting of pine needle powder, pine resin powder, wormwood powder and Chinese juniper powder in the amount of 0.5-1wt%, and they are added before kneading the mixture.
