Dynamic correlation function of fluctuation field in a dirty superconductor is investigated above the transition point. It is determined self-consistently in the critical range of temperature where the mean field theor breaks down and interactions among fluctuation modes must be taken into account. Correlation function is of diffusional type with a diffusion constant which becomes singular as (T/T_c-1)^<1-(4/d)> where d is dimensionality. The inverse correlation length is proportional to (T/T_c-1)^<2/d> and is independent of mean free path of electron. Electrical conductivity of a bulk system in the critical range contains a term which in creases like (T/T_c-1)^<-1/3> and which is independent of mean free path. However in a case of a film system a problem arises.
