An attempt is made to present some experimental predictions of Higgs in the Randall-Sundrum model. We investigate the production of Higgs via $e^{+}e^{-}$ and $\gamma\gamma$ colliders including the radion-Higgs mixing parameters. The production cross-sections in $e^{+}e^{-}$ collisions are much larger than that in $\gamma\gamma$ collisions in the same conditions. The decay widths of Higgs depend strongly on the radion mass and the vacuum expectation value of the radion, so the existence of radion in the Randall-Sundrum model is necessary. The results also show that the dominant decay mode is $h \rightarrow b \overline{b}$. \\ Keywords: radion-Higgs mixing, decay widths, Randall-Sundrum model.
