The possibility that the s-d interaction gives rise to a bound state between conduction electrons and localized spin in a superconductor is discussed. It is shown that a singlet bound state is energetically favorable when lambda sub zero is greater than delta, where lambda sub zero is the binding energy of the singlet in the normal state and delta is the zero temperature BCS gap parameter.
