We discuss a Higgs inflation model in the warped DGP braneworld background. It generates reasonable primordial perturbations. At the same time, with enhanced nonminimal coupling, it overcomes the severe problem in the Higgs inflation in four dimensions, which. says that the effective field theory becomes invalid at an energy scale far below the energy scale for inflation exit. Furthermore, we present the constraints for the parameters confronted to PLANCK and related observations. PLANCK low-l data almost fixes the inflation energy scale in this Higgs inflation model with specific brane parameters.
