PROBLEM TO BE SOLVED : To provide a catalytic cracking catalyst of a hydrocarbon oil enabling a gasoline fraction having high octane value and LPG having high content percentage of propylene and butene to be produced while suppressing increase in yield of a heavy fraction. SOLUTION : The catalytic cracking catalyst of a hydrocarbon oil is provided which contains : zeolite having a sodalite cage structure having a lattice constant of 2.430 to 2.445 nm; a silicon atom derived from silica sol; a phosphorus atom and an aluminum atom derived from primary aluminum phosphate; rare earth metal; and clay mineral each in a predetermined amount. In the catalytic cracking catalyst of a hydrocarbon oil, a ratio of content percentage of the phosphorus atom and the aluminum atom derived from the primary aluminum phosphate in terms of Al2O3 3 P2O5 to content percentage of the aluminum atom existing in a unit lattice skeleton of the zeolite in the catalytic cracking catalyst is 0.01 to 0.45, and a ratio of content percentage of the rare earth metal in terms of oxide to the percentage content of the aluminum atom existing in a unit lattice skeleton of the zeolite in the catalytic cracking catalyst is 0.003 to 0.27.
