The Cosserat continuum theory or theory of polar materials intends to reflect thhe effects of microscopic structures into the macroscopic behavior of materials. In contrast with the effects of mechanical microstructures of these theories, in this paper, thermodynamical microstructures are taken into consideration. A previous report called these materials "thermopolar materials". The Clausius-Duhem inequality is intoduced, including the terms of the temperature gradient. Using this inequality, constitutive equations are obtained, and it is made clear that the values of stresses or thermodynamical quantities under nonequilibrium condition; are different from the values under local equilibrium conditions. Also, in the constitutive equation for stress, "temperature gradient stress" of a positive value is introduced.
