Disclosed is a new exhaust gas purifying catalyst carrier having excellent catalytic activity, particularly at low temperatures, and an exhaust gas purifying catalyst containing the exhaust gas purifying catalyst carrier and a catalytically active component. A catalytic active component is supported on a catalyst carrier composed of particles containing silicate or phosphate containing one or more of elements belonging to Group 1 and Group 2 of the periodic table. Exhaust gas purification catalyst. The silicate is Ca, Sr or Ba or two or more of these. In the case of the phosphate, x is 2 or 1.5 in the composition formula represented by A x PO 4 , and x is 2 In the case of A, a combination of one or more monovalent elements of Li, Na, K or Cs and one or more divalent elements of Mg, Ca, Sr or Ba, x = 1. In the case of 5, the carrier comprising a divalent element. [Selection figure] None |
