Abstract
A silver halide emulsion comprising silver halide grains. In them, 60 or more percent of the total area of all silver halide grains are occupied by tabular silver halide grains having a circle equivalent diameter of 0.6 .mu.m or less, an aspect ratio of 1.5 or more, and having dislocation lines substantially localized only in the fringe portions thereof. Also, 50 or more percent of the number of all silver halide grains are occupied by tabular silver halide grains having 10 or more dislocation lines per grain. In addition, the surface silver iodide content of all silver halide grains is 3 mol % or less when analyzed by X-ray photoelectric spectroscopy (XPS).
