Behaviors of conductivity and dielectric constant near Anderson transitionare investigated within one-electron theory using renormalization group technique.It is shown that conductivity and dielectric constant depend on a controllableparameter x like o(,?x -,X".l' and z.?x -,X'.l =", respectively, and that the prefactorssatisfy the relation og(zg=CQv0where v, is the density of state at Fermi leveland C is a constant which is independent of the details of the microscopic structureof the system. In the absence of magnetic field and magnetic scattering of electrons,for instance, C is e'(2/m')""/A.
