    The flux upper limits of the diffuse gamma rays, from the inner and outer Galactic planes, are found to be decreased by factors of 4.0∼3.6 for 3∼10 TeV, respectively, by using the simulation results of effective area ratios for gamma-ray and cosmic-ray induced showers in the Tibet air shower array. In our previous work, the flux upper limits were deduced only from the flux ratio of air showers generated by gamma rays versus cosmic rays. As a result the source electron spectral index for inverse Compton should be steeper than 2.2 and 2.1 for the inner and outer Galactic planes, respectively.
