A method of manufacturing PTA oxidized catalyst with lower corrosion, the oxidized catalyst is brominated cobalt manganese acetate in solution with a weight ratio of Co/Mn/Br being in a predetermined ratio. When the brominated cobalt manganese acetate in solution meets a condition (Cox2.7)+(Mnx2.9)>Br, CoBr<SUB>2</SUB>, MnBr<SUB>2</SUB>, cobalt acetate and manganese acetate are used as sources for manufacturing; when the brominated cobalt manganese acetate in solution meets the condition (Cox2.7)+(Mnx2.9)<BR, COBR<SUB>2</SUB>, MnBr<SUB>2 </SUB>and micro amount of bromine are used as sources for manufacturing without adding or with adding therein only with micro amount of HBr, corrosiveness of the oxidized catalyst is lowered.
