We suggest that the meson is a dynamical gauge boson of a hidden local symmetry in the non-linear chiral Lagrangian. The origin of the -meson mass is understood as the Higgs mechanism of the hidden local symmetry. The low-energy dynamics of, , and matter fields, including the Kawarabayashi-Suzuki-Riazuddin-Fayyazuddin relation and -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 dominance of the photon coupling.
