PROBLEM TO BE SOLVED: To provide a catalyst which can be used for producing a variety of diesel oil with advantages such as outstanding hydrogenation cracking proper ties and hydrogenation dewaxing properties, the high quality of obtained hydro genation cracked finished products, and the wide distillation range of a diesel fraction which can be used for the production of especially, the diesel oil at a low freezing temperature. SOLUTION: This hydrogenation cracking catalyst has the SiO2 /Al2 O3 ratio of 30-90, the acidity of 0.1-0.5 mmol/g and the moisture adsorption power of 10 wt.% or less when a temperature is 25 deg.C and a steam pressure is 12 mmHg or less. In addition, the catalyst is composed of 5-40 wt.% of modified superhydrophobic zeolite-β, 10-50 wt.% of amorphous silica-alumina, 15-30 wt.% of alumina, 10-40 wt.% of at least, one of group VIb metallic oxide and 1-10 wt.% of at least, one of group VIII metallic oxide.
