The proximity effect of a thin normal metal layer in a superconductor is inves-tigated by solving the phenomenological Ginzburg-Landau equations. Thethickness of the normal layer is assumed to be much smaller than the electronmean free path. The degradation of the induced order parameter in the normallayer from the bulk superconductivity is proportional to both the repulsivepotential for Cooper pairs in the normal layer and its thickness. It is elucidatedthat the superconductivity is degradated also in the superconducting region inthe vicinity of the normal layer. The present result is compared with the result ofthe McMiIIan's tunneling theory.
