Stellar flares create sudden bursts of hot plasma that contain a wide range of
temperatures, and are capable of generating 6.7 keV Fe XXV emission line via electronic
collisional excitation. Using the measured 6.7 keV fluxes from a collection of Suzaku
observed stellar flares as a baseline, we estimate their contribution to the 6.7 keV
emission line from the Galactic Ridge X-ray emission (GRXE). We modeled the extracted
stellar flares spectra from our sources with a simple power law. We found strong 6.7 keV
emission line from the extracted stellar flares spectra which is similar to the observed
6.7 keV emission line from the GRXE, while the 6.4 and 7.0 keV lines are completely
absent except in one of the sources, V773 TAU with 7.0 keV line.  The present result
shows that stellar flares are major contributor to the 6.7 keV line emission from the
GRXE, and contributes more to this line that others like hard X-ray emitting symbiotic
stars (hSSs), and magnetic cataclysmic variables (mCVs), along with other white dwarf
binary systems, which are known to contribute significantly to the Fe K_alpha emission
line from the GRXE, especially the 6.4 keV and 7.0 keV emission lines.
