A relay welding diagnosing apparatus can lower a risk of erroneous diagnosis while preventing energy of a battery from being discharged uselessly. The relay welding diagnosing apparatus including a positive electrode side relay, a negative electrode side relay, and a capacitor and a load circuit that are connected in parallel between the positive electrode side relay and the negative electrode side relay, which is forced discharge, by connecting the capacitor and the load circuit; and a determining section that, in a case where the negative electrode side relay is not welded, determines whether or not the positive electrode side relay is welded after the active discharge is performed and, in a case where the negative electrode side relay is welded, determines whether or not the positive electrode side relay is welded after passive discharge of the capacitor, which is natural discharge, is performed.
