An exhaust gas purifying catalyst having a high purifying ability even if noble metal is not used as an essential component, an exhaust gas purifying monolith catalyst, and a method for manufacturing an exhaust gas purifying catalyst, are provided. The exhaust gas purifying catalyst includes an oxide having an oxygen storage and release capacity, and an oxide represented by the following formula (1) supported on the oxide having the oxygen storage and release capacity, LaxM1-xM'O3-delta(1) (wherein La represents lanthanum, M represents at least one element selected from the group consisting of barium (Ba), strontium (Sr) and calcium (Ca), M' represents at least one element selected from the group consisting of iron (Fe), cobalt (Co), nickel (Ni) and manganese (Mn), delta represents an oxygen deficient amount, and x and delta fulfill conditions represented by 0<x@1 and 0@delta@1, respectively). |
