<；P>；PROBLEM TO BE SOLVED: To provide a flame-retardant filter medium for gas removal, one filter medium of which has both functions of decomposing ozone and adsorbing VOC while keeping flame retardancy. <；P>；SOLUTION: The flame-retardant filter medium for gas removal is obtained by depositing an impregnated activated carbon particle, which is obtained by impregnating an activated carbon particle with potassium carbonate and/or potassium hydrogen carbonate, on a cover material which contains a flame retardant and consists of a woven fabric. The amount M(%) of potassium carbonate and/or potassium hydrogen carbonate to be impregnated is &ge；1 mass%. The flame-retardant filter medium for gas removal satisfies inequality (1): S&ge；200M+550 (wherein M is the amount (%) of potassium carbonate and/or potassium hydrogen carbonate to be impregnated； S is the specific surface area (m<；SP>；2<；/SP>；/g) of the activated carbon particle, which is measured by a BET method). <；P>；COPYRIGHT: (C)2009,JPO&INPIT
