The present invention provides a hydrocarbon oil hydrotreating catalyst that has excellent desulfurization activity and can regenerate a high-performance catalyst. [MEANS FOR SOLVING PROBLEMS] For example, molybdenum and / or tungsten is supported in an amount of 15 to 30 parts by mass in terms of oxide, and cobalt and / or nickel in terms of oxide is 3 to 100 parts by mass on an inorganic oxide support. The amount of carbon supported by 7 parts by mass and derived from the organic acid is 2.0 parts by mass or less on an element basis. Moreover, the specific surface area of a catalyst is 140-350 m < 2 > / g, and the average pore diameter measured by the mercury intrusion method is 50-130 mm. Also, the loss of ignition of the catalyst is 5.0% or less, the peak temperature of desorbed water in the range up to 450 ° C. is 415 ° C. or less, based on the temperature reduction method of the catalyst, the adsorption amount of nitric oxide of the sulfurized catalyst Is 8.0 ml / g or more.
