The role of the inverse Compton interaction for production of gamma-rays of energy greater than 100 MeV in the Galaxy is investigated. The cosmic-ray electron density is considered to be either constant or varying in the Galaxy, in accordance with current ideas about the relationship among cosmic rays, magnetic fields, interstellar gas, and the galactic spiral structure. The stellar photon intensity is estimated using models of mass distribution in the Galaxy. Contribution of the 2.7-K background radiation is included. It is found that the gamma-ray flux from the galactic-center direction, produced by this process, is lower than that measured by the SAS-2 satellite by an order of magnitude.
