A hydrocracking catalyst for heavy hydrocarbon oils comprising a metallic element of the VIb Group and a metallic element of the VIII Group supported on a carrier containing a novel faujasite-type aluminosilicate which absorbs an infrared in a frequency region of 3740 10 cm-1 in an absorption percentage A of at least 20 % and absorbs an infrared in a frequency region of 3560 10 cm-1 in an absorption percentage B of at least 5 %, the ratio of A/B being at least 2, has a specific surface area of at least 650 m2/g, has a framework SiO2/Al2O3 molar ratio of from 20 to 50, and has a lattice constant of from 24.15 to 24.50.ANG. . The novel faujasite-type aluminosilicate is produced by treating a faujasite-type zeolite with an acid.
