Abstract
In this report we presentmeasurements of Galactic Ridge X-ray Emission (GRXE) in the Galactic Center region using INTEGRAL scanning observations. The 25-60 keV band GRXE fluxes at l = 0°, l = -22.5°, and l = +22.5° are 154±15, 72±15, and 62±12 mCrab, respectively. The derived longitude profile of the GRXE is in good agreement with the Galactic distribution of stars obtained from infrared observations, which strongly indicates its stellar origin.
