What is claimed is: 1. A hydrotreating catalyst comprising molybdenum (Mo), a phosphorus compound, sulfur and at least one metal selected from the group consisting of iron, cobalt and nickel, wherein the average coordination number [N(Mo)] of the molybdenum atoms around the molybdenum atom is from 1.5 to 2.5 and the average coordination number [N(S)] of the sulfur atoms around the molybdenum atom is from 3.5 to 5.0 when MoS2 structure in the catalyst is measured in accordance with extended X-ray absorption fine structure (EXAFS) analysis, and wherein the molybdenum is contained in an amount of 6 to 15% by weight in terms of oxide, based on the weight of the catalyst. 2. The hydrotreating catalyst according to claim 1, wherein the at least one metal selected from the group consisting of iron, cobalt and nickel is contained in an amount of 0.5 to 8% by weight in terms of oxide, based on the weight of the catalyst. 3. The hydrotreating catalyst according to claim 1, wherein the phosphorus compound is selected from the group consisting of ammonium dihydrogen phosphate, diammonium hydrogen phosphate, trimetaphosphoric acid, pyrophosphoric acid, and tripolyphosphoric acid. 4. The hydrotreating catalyst according to claim 1, wherein the phosphorus compound is contained in an amount of 0.5 to 10% by weight in terms of metal, based on the catalyst. 5. The hydrotreating catalyst according to claim 1, which is produced by impregnating a support with an impregnating solution comprising a molybdenum compound, a phosphorus compound, a saccharide compound and at least one metal selected from the group consisting of iron, cobalt and nickel, followed by drying under irradiation with a microwave. 6. The hydrotreating catalyst according to claim 5, wherein the saccharide compound is at least one selected from aldonic acids, saccharic acids and uronic acids. 7. The hydrotreating catalyst according to claim 6, wherein the aldonic acid is gluconic acid. 8. A process for producing the hydrotreating catalyst according to claim 1, which comprises impregnating a support with an impregnating solution comprising a molybdenum compound, a phosphorus compound, a saccharide compound and at least one metal selected from the group consisting of iron, cobalt and nickel, followed by drying under irradiation with a microwave. 9. The process according to claim 8, wherein the saccharide compound is at least one selected from aldonic acids, saccharic acids and uronic acids. 10. The process according to claim 9, wherein the aldonic acid is gluconic acid.
