A silver iodide fine grain emulsion comprising a dispersion medium and fine grains of silver iodide has an average grain size of 0.02 to 0.07 mu m, contains 0.6 mol or more of silver iodide per liter thereof in a dissolved state at 40 DEG C., and has an electric conductivity of 4,500 to 15,000 mu S/cm in a dissolved state at 40 DEG C. A lightsensitive silver halide emulsion produced by using the above silver iodide fine grain emulsion is also disclosed. A silver halide photographic lightsensitive material comprising a support and, superimposed thereon, at least one lightsensitive silver halide emulsion layer in which the above lightsensitive silver halide emulsion is contained, is also disclosed.
