PROBLEM TO BE SOLVED: To obtain a deodorant for a composite offensive odor which shows high efficiency in deodorizing an aldehyde series gas difficult to be deodorized by the conventional method while the deodorizing capacity for acidic, alkaline and sulfuric gases is maintained. SOLUTION: The characteristics of the deodorant for the composite offensive odor of this invention are that (1) an acid salt of p-aminobenzoic acid, an inorganic salt, bromine and/or a bromide are carried with a porous body, and the carrying quantities (2) of the deodorant components for the composite offensive odor described in (1) are that when the weight of the porous body is 100 pts.wt., the weight of the p-aminobenzoic acid or its acid salt is 0.5-20 pts.wt., the weight of the inorganic acid is 1-20 pts.wt. and the weight of the bromine and/or the bromide is 1-20 pts.wt.
