PROBLEM TO BE SOLVED: To produce a catalyst for hydrogenation refining with heightened desulfurization and denitrification capacity using a small amount of metal deposition by improving the dispersibility of the metals to be deposited and keeping a high volume of pores valid to a reaction and to provide a method for hydrogenation refining using the catalyst. SOLUTION: This catalyst for hydrogenation refining comprises a silica- alumina type catalyst support and a molybdenum component, a nickel component, and a cobalt component deposited on the support. In the catalyst for hydrogenation refining, the metal mole ratio [Mo], [Ni], [Co] of the molybdenum component, the nickel component, and the cobalt component, respectively, are controlled to satisfy the followings: 0.5<[Co]/[Ni]+[Co]<0.75; 0.2<[Ni]+[Co]/[Mo]<0.5: and the fine pore volume of fine pores with 60-90Åis controlled to be 0.3-0.7 cc/g.
