We suggest that the rho meson is a dynamical gauge boson of a hidden local symmetry in the nonlinear chiral Lagrangian. The origin of the rho-meson mass is understood as the Higgs mechanism of the hidden local symmetry. The low-energy dynamics of rho, ..pi.., and matter fields, including Kawarabayashi-Suzuki-Riazuddin-Fayyazuddin and rho-coupling universality, is consistently described in this new framework. The electromagnetic interaction can be introduced in a unique manner, which gives a successful explanation of rho dominance of the photon coupling.
