  The kappa-distributed fully ionized plasma with collisional interaction is
investigated. The Fokker-Planck equation with Rosenbluth potential is employed
to describe such a physical system. The results show that the kappa
distribution is not a stationary distribution unless the parameter kappa tends
to infinity. The general expressions of collisional relaxation rate of
multiple-component plasma with kappa distribution are derived and discussed in
specific cases in details. For the purpose of visual illustration, we also give
those results numerically in figures. All the results show that the parameter
kappa plays a significant role in relaxation rate.
