PROBLEM TO BE SOLVED: To produce a catalyst for hydrocracking wax-containing raw material oil, which is used when the wax-containing raw material oil is hydrotreated and with which a kerosene/light oil fraction having excellent quality is obtained with high selectivity in high yield, and to provide a method for manufacturing the catalyst and a method for hydrocracking the wax-containing raw material oil effectively by using the catalyst. SOLUTION: This catalyst for hydrocracking the wax-containing raw material oil is obtained by depositing a noble metal component on a carrier and has such a characteristic that the ratio A/B of the concentration degree A of the noble metal on the outside surface of this catalyst to that B of the noble metal in the center of this catalyst is 0.2-2 when the concentration distribution of the noble metal in the cross section of this catalyst is measured by an electron probe microanalysis (EPMA).
