Abstract
Provided are an exhaust gas purifying catalyst having high catalytic activity enabling combustion of PM at low temperatures and free from any risk of dispersal of metal elements arousing concern about environmental load, an exhaust gas purification device and filter having a high combustion efficiency of PM, and a method for producing the catalyst. An exhaust gas purifying catalyst contains: an oxide containing at least one element (A) selected from alkali metals and alkaline earth metals and at least one element (B) selected from Zr, Si, Al, and Ti; and a cesium salt.
