We report the theoretical study on the thermal spin transport in ferromagnetic insulators. By using the fluctuation-dissipation theorem, we derive a random torque acting on the magnetic moment at the finite temperature. The numerical results shows the propagating spin wave that is driven by the thermal gradient. Furthermore, we argue a measurable voltage induced by the inverse spin Hall effect by using realistic parameters of actual setup.
