We investigate the BRS quantization of a gauge theory in which the Killing metric is replaced with a function of scalar fields. This type of gauge theory becomes important when we discuss internal gauge symmetries based on noncompact Lie groups. We point out that, in order to assure the BRS invariance, the Lagrangian density must contain fourth order terms of FP (anti-) ghost fields. It is also shown that a part of the gauge fields becomes massive and their propagator has the same high-energy behavior as that of massless gauge fields.
