Properties of the domain wall (kink) solution in the 5 dimensional RandallSundrum model are examined both analytically and numerically. The configuration is derived by the bulk Higgs mechanism. We focus on 1) the convergence property of the solution, 2) the stableness of the solution, 3) the non-singular property of the Riemann curvature, 4) the behaviours of the warp factor and the Higgs field...
