A spatial dependence of an order parameter around a single paramagnetic impurity in the superconductor is investigated at finite temperatures below the transition temperature, including the absolute zero temperature. The self-consistent integral equations for the order parameter are set up and are solved for the order parameter at those space points, of which distance from the impourity is greater than the coherence length. In this work we use the scattering t-matrices for a perturbational method and for a classical spin. The order parameter shows a weak long range variation. The calculational procedure beyond our approximation as well as the Kondo effect on the spatial variation is discussed.
