PROBLEM TO BE SOLVED: To reduce various adverse effects due to the multilayer adsorption of a sensitizing dye by specifying the coefficient of variation in the inter-grain distribution of light absorbance to be a specified percentage or lower. SOLUTION: In the silver halide photographic emulsion containing a sensitizing dye multilayer-absorbed on the surfaces of silver halide grains, the coefficient of variation in the inter-grain distribution of light absorbance is <=100%. When the maximum value of spectral absorbance of the sensitizing dye is represented by Amax, the coefficient of variation in the inter-grain distribution at the wavelength interval between the shortest wavelength and the longest wavelength both showing Amax of 50% is preferably <=50%. The fluctuation width of wavelength of the spectral absorption maximum of grains occupying >=50% of the total projected area of all the silver halide grains in the emulsion is preferably <10 nm. the sensitizing dye of the 2nd layer to the top layer is preferably present in a stratiform state. When the optical density at the wavelength of spectral absorption maximum before photographic processing and that after photographic processing are represented by G0 and G1, respectively, the ratio of G1 to G0 is preferably <=0.9.
