The thermodynamical quantities around a dilatonic black hole are investigated by using the brick-wall method. It is shown that any one of these quantities contains an additional spin-dependent term due to the spin field and that the usual results that the entropy density, energy density and pressure take the same forms as those in flat spacetime hold only for the leading term.
