  ~It is shown that the quantum massive non-Abelian field theory established in
the former papers is renormalizable. This conclusion is achieved with the aid
of the Ward-Takahashi identities satisfied by the generating functionals which
were derived in the preceding paper based on the BRST-symmetry of the theory.
By the use of the Ward-Takahashi identity, it is proved that the divergences
occurring in the perturbative calculations for the massive gauge field theory
can be eliminated by introducing a finite number of counterterms in the
effective action. As a result of the proof, it is found that the
renormalization constants for the massive gauge field theory comply with the
same Slavnov-Taylor identity as that for the massless gauge field theory. The
latter identity is re-derived from the Ward-Takahashi identities satisfied by
the gluon proper vertices and their renormalization.
