Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a silver halide emulsion possessing a uniform halide distribution. SOLUTION: When a part or the whole of halide with higher atomic number is dissolved in silver salt aqeuos solution and the obtained solution is introduced into an emulsion production process in any stage, silver halide, which is provided with a more uniform halide distribution among an individual grain, among a certain area from a grain to a grain, or among the whole volume and is provided with at least two kinds of halides with different atomic numbers, can be produced.
