A renormalization scheme of a canonical Yang-Mills field theory porposed previously is applied to the SU(2) Higgs-Kibble model. After the spontaneous breakdown of symmetry under the gauge group SU(2), a complex spinor scalar field is represented by its components being assigned as a singlet and a triplet of the global gauge group, while it still corresponds to a doublet under the Becchi-Rouet-Stora transformation. The transformation properties of these components under a q-number local gauge transformation, which varies values of gauge parameters, are exactly determined. The triplet corresponds to a massless Goldstone-boson field, and it exhibits a dipole-ghost character, the origin of which is due to a gaugeon field introduced into the theory. The Becchi-Rouet-Stora symmetry presents a useful piece of information about vacuum expectation values of field commutators, as well as it guarantees the unitarity of a physical S-matrix. All renormalization constants are given as being independent of gauge parameters.
