    摘要： [Object] To provide an oxidation catalyst composition excellent in low temperature activity and a PM oxidation catalyst which can oxidize or burn particulate and the like from an internal combustion engine even at relatively low temperatures. [Solving Means] An oxidation catalyst composition contains cerium, manganese, and a metal M (M is a trivalent metal element excluding cerium). When the oxidation catalyst composition is analyzed by XPS so that orbital energies are subjected to peak separation using the Gaussian function, the Ce4+/Ce3+ atomic weight ratio (atomic % ratio) is 1.7 or higher and Mn2+ is in an amount of 5 atomic % or larger, wherein at least a part of the oxidation catalyst composition forms a composite. The above-mentioned metal M is ytterbium, thulium, erbium, holmium, dysprosium, gadolinium, europium, samarium, promethium, neodymium, praseodymium, scandium, yttrium, aluminum, gallium and/or the like.
