Provided is a method for easily manufacturing a catalytic cracking catalyst for hydrocarbon oil having high cracking activity when used on heavy hydrocarbon oil and allowing production with a high yield ratio of a gasoline fraction with a high octane value. A method for manufacturing a catalytic cracking catalyst for hydrocarbon oil, characterized in that when the solid content is converted, an aqueous slurry is produced containing 20-50 mass% of a zeolite having a sodalite cage structure, 10-30 mass% of silica sol in terms of SiO2 conversion, 0.1-21 mass% of a first aluminum phosphate in terms of Al2O3⋅3P2O5 conversion, and 5-65 mass% of a clay mineral, after which the slurry is aged for 5-200 minutes and then spray-dry processed. |
