The Hawking radiation for massless spin-2 fields is numerically studied whenthe spacetime background is (4+n)-dimensional Schwarzschild black hole phase.In order to check the validity of the Emparan-Horowitz-Myers argument, {\itblack holes radiate mainly on the brane}, we assume that the radial equationfor the massless spin-2 fields propagating on the brane obeys the masterequation approximately. The transmission coefficient is computed explicitly bymaking use of the Hawking-Hartle theorem. It is shown that the total emissionrates into the bulk are dominant compared to the rates on the visible branewhen $n \geq 3$. However, the bulk-to-brane relative emissivities per degree offreedom always remain O(1) roughly. The experimental significance of theseresults in the production of mini black holes in future colliders is brieflydiscussed.Comment: V1:9 pages, 4 figures, V2: some typos corrected in reference V3:  title changed, final version, appear in MPL
