To provide an ion exchange membrane with a catalyst layer, an ion exchange membrane and an electrolytic hydrogenation apparatus, which can lower electrolysis voltage and increase current efficiency at the time of electrolytic hydrogenation of an aromatic compound.The ion exchange membrane with a catalyst layer of the present invention has an inorganic particle layer containing inorganic particles and a binder, a layer (Sa) containing a first fluorinated polymer having sulfonic acid type functional groups, and a layer (Sb) containing a second fluorinated polymer having sulfonic acid type functional groups, and a catalyst layer, in this order, wherein the ion exchange capacity of the above first fluorinated polymer is lower than the ion exchange capacity of the above second fluorinated polymer.
