ABSTRACT:
A silver halide photographic emulsion contains tabular silver halide grains having an aspect ratio of 2 or more in an amount of 70% or more of a total projected area of all grains. A variation coefficient of the grain size distribution of all silver halide grains is 20% or less, a signal having at least two peaks is present in a diffraction angle range of less than 1.5 degree at a maximum peak height.times.0.13 of a (420) X-ray diffraction signal obtained using the K.sub..alpha. line of Cu, and a peak interval thereof is 0.1 degree or more in terms of the diffraction angle.
