By the use of Ginzburg-Landau equadons, which include the effect arising from the sinusoidal variadon of the impurhy concentradon in one dlrection, the stabinty of variety of the vortex lattice configuradon in the type II superconductors is studied. In the vicinhy of the upper critical field H_<c2>, the critical current is determined as a function of the external field, which is compared with a recent experiment by Raffy et al, The present theory describes semi-quantitatively the observed field dependence of the critical current.
