PROBLEM TO BE SOLVED: To provide a method for producing a high octane value gasoline substrate, by which a fraction capable of being used as a gasoline substrate having a high octane value and a low sulfur content can profitably and efficiently be produced from fractions except a gasoline fraction. SOLUTION: This method for producing the high octane value gasoline substrate is characterized by contacting a petroleum-based hydrocarbon having a boiling point range of 140 to 360°C and containing aromatic hydrocarbon compounds in an amount of at least 40 mass% with a catalyst prepared by carrying at least one hydrogenated active metal selected from the group VIII metals and the group VI metals in the periodical table on crystalline aluminosilicate zeolite containing particles having particle diameters of≤0.5μm in an amount of≥80 vol.% and obtained by crystallizing a mixture of a silica source, an alumina source, an alkali source, water and a diglycolamine, in the presence of hydrogen to produce the gasoline substrate having a research octane value of≥90 and a sulfur content of≤10 mass ppm.
