An object of the present invention is to provide a method for producing an eggshell membrane lot capable of easily and efficiently obtaining an eggshell membrane lot and a method for producing an egg-related product group using the eggshell membrane lot production method. An egg shell with eggshell membrane is prepared by splitting eggs to remove egg white and egg yolk from the eggshell to prepare an eggshell with eggshell membrane, and using the difference in specific gravity between the eggshell membrane and eggshell from the eggshell with eggshell membrane. An eggshell membrane lot separation step for separating an eggshell membrane to obtain an eggshell membrane, wherein the eggshell membrane separation step corresponds to the eggshell membrane lot and includes a plurality of eggshell membrane-attached eggshells. A raw material lot that is composed of 85 to 95% by number of eggshells with eggshell membranes formed by dividing an egg of 64 g or more is used.
