To obtain an impregnation liquid for producing a hydrogenation catalyst indicating high activity in which a main active component such as Mo and W and a co-active component such as Co and Ni are dissolved stably.
In the impregnation liquid for producing the hydrogenation catalyst, at least one first ion selected from ions including Mo and ions including W and at least one second ion selected from ions including Co and ions including Ni coexist, mainly the second ion out of the first and second ions substantially exists as a complex ion in which the second ion is coordinated with a chelating agent. The logarithm of the equilibrium constant in the generation reaction of the complex ion produced from the chelating agent and the first ion is 5 or below, and the logarithm of the equilibrium constant in the generation reaction of the complex ion produced from the chelating agent and the second ion is at least 15.
