  We present the results of a Suzaku study of a bright point-like source in the
6.7 keV intensity map of the Galactic center region. We detected an intense
FeXXV 6.7 keV line with an equivalent width of ~1 keV as well as emission lines
of highly ionized Ar and Ca from a spectrum obtained by the X-ray Imaging
Spectrometer. The overall spectrum is described very well by a heavily absorbed
(~2x10^{23}cm^{-2}) thin thermal plasma model with a temperature of 3.8+/-0.6
keV and a luminosity of ~3x10^{34} erg s^{-1} (2.0--8.0 keV) at 8 kpc. The
absorption, temperature, luminosity, and the 6.7 keV line intensity were
confirmed with the archived XMM-Newton data. The source has a very red
(J-Ks=8.2 mag) infrared spectral energy distribution (SED), which was fitted by
a blackbody emission of ~1000 K attenuated by a visual extinction of ~31 mag.
The high plasma temperature and the large X-ray luminosity are consistent with
a wind-wind colliding Wolf-Rayet binary. The similarity of the SED to those of
the eponymous Quintuplet cluster members suggests that the source is a WC-type
source.
