The entropy densityenergy density and pressure of the spin fields near the event horizon in Taub-NUT spacetime are investigated by using the Wentzel-Kramers-Brillouin approximation. It is shown that any one of the thermodynamic quantities has three terms. The first term has the same form as that in flat spacetime, the second and the third terms are spin-dependent terms due to the spin fields.
