The low-frequency dielectric relaxation of oxide glass is ascribed to Maxwell-Wagner effect due to the microscopic conducting path structure. The Maxwell-Wagner effect of a special type of inhomogeneous conductor consisting of inclined layers with different local conductivities is investigated and the following findings are made: (1) The exceptional temperature dependence of the low-frequency dielectric relaxation of some electronic conducting oxide glasses is ascribable to the effect of the local conductivity of the nonconductive region. (2) The multiple dielectric relaxation of some mixed alkali oxide glasses is attributable to a special type of conducting path structure with two kinds of conducting paths. (3) The shape of the conducting path of oxide glass is highly complicated.
