PROBLEM TO BE SOLVED: To provide a hydrogenation catalyst for an aromatic hydrocarbon, which can suppress formation of by-products.SOLUTION: The hydrogenation catalyst for an aromatic hydrocarbon, pertaining to one aspect of the present invention, comprises an active component containing an active metal element and an additive element. The active metal element is one selected from the group consisting of nickel, palladium, and platinum, and the additive element is one selected from the group consisting of tin, germanium, gallium, copper, and iron. When a diffraction angle of diffracted X-rays derived from a crystal structure of a simple substance m of the active metal element is dm, an X-ray diffraction spectrum of the active component has a maximum value at a diffraction angle da which is different from the diffraction angle dm. |
