Temperature distributions of the electron and lattice systems induced by the Peltier effect have been precisely measured by improved Harman method, where the temperature differences ($\Delta T_{\text{el}}$ and $\Delta T_{\text{la}}$) have been independently evaluated for several terminal lengths ($L_{\text{V}}$) in thermoelectric materials (Bi,Sb)2Te3. Both temperature distributions have different behaviors in the stationary state, that is, the $L_{\text{V}}$ dependences of $\Delta T_{\text{el}}$ and $\Delta T_{\text{la}}$ show positive and negative curvatures, respectively. It is also indicated that the temperature difference has a linear relation to $L_{\text{V}}$ in the whole system and the observed non-equilibrium phenomenon is consistent with a law of the conservation of heat quantity.
