To provide an exhaust gas purification catalyst or the like in which poisoning of a noble metal component by a Si-containing compound generated or detached from silicon carbide is inhibited, degradation of exhaust gas purification performances is inhibited over a long period and long-term durability is excellent. An exhaust gas purification catalyst 100 having a stacked structure including at least a substrate 10, a first coat layer 11 and a second coat layer 21 in the listed order, in which the substrate 10 is one selected from the group consisting of a silicon carbide carrier including silicon carbide and a silicon carbide-covering carrier on which a coating layer including silicon carbide is provided, the first coat layer 11 includes a compound including one or more alkaline-earth metals selected from the group consisting of magnesium (Mg), calcium (Ca), strontium (Sr), and barium (Ba), and the second coat layer 21 includes one or more platinum group elements selected from the group consisting of rhodium (Rh), platinum (Pt), and palladium (Pd).
