PROBLEM TO BE SOLVED: To provide a method for treating exposed silver halide emulsion layer, a hologram manufactured by the method and a hologram optical element containing the same. SOLUTION: This method for treating exposed silver halide emulsion layer comprises a step 40 of pre-hardening an exposed emulsion layer, a step 50 of developing the pre-hardened emulsion layer, a step 60 of bleaching the emulsion layer after development, a step 70 of subjecting the emulsion layer after the bleaching to the first hardening (the first curing), a step 80 of subjecting the emulsion layer after the first hardening to the first drying, a step 90 of subjecting the emulsion layer after the first drying to the second hardening (the second curing), a step 100 of subjecting the emulsion layer after the second hardening to fixing treatment, a step 110 of subjecting the silver halide emulsion layer which is subjected to the fixing treatment to hot water treatment and a step 120 of subjecting the silver halide emulsion layer which is subjected to hot water treatment to the second drying.
