This deodorant comprises a crystalline zinc oxide obtained by conjugating zinc oxide and aluminum oxide, the deodorant being characterized in that the mole ratio (ZnO/Al2O3) of the zinc oxide to the aluminum oxide is 40-80. As a result, it is possible to obtain a strong deodorizing effect against sulfur gases and acidic gases. A favorable average particle diameter for the deodorant is 0.2-15[mu]m.
