Keywords:entropy, spin current, bipolar conductor

We formulated the entropy production rate in bipolar conductors in terms of heat current density, charge current density, hole spin current density, and electron spin current density. It follows from our formulation that not only spin current but also the difference between the hole and electron spin currents contribute the entropy production.
