The present disclosure relates to a method for manufacturing carboxymethyl cellulose particles, cellulose inducer particles manufactured by the method, and an absorbent article comprising same. The method comprises: (1) a step of obtaining alkalized cellulose by reacting a cellulose raw material with an alkalizer; (2) a step of obtaining carboxymethyl cellulose by reacting the alkalized cellulose with a carboxy methylating agent; (3) a primary cross-linking step of obtaining a slurry-phase carboxymethyl cellulose cross-linked body by reacting the carboxymethyl cellulose with a core cross-linker; (4) a step of washing and dehydrating after filtering the slurry-phase carboxymethyl cellulose cross-linked body; (5) a secondary cross-linking step of obtaining carboxymethyl cellulose having a core-shell structure by reacting the carboxymethyl cellulose cross-linked body having undergone Step (4) with a surface cross-linker; and (6) a step of obtaining carboxymethyl cellulose particles having a core-shell structure by drying and pulverizing the carboxymethyl cellulose having a core-shell structure.
