SUBJECT of the Invention Provide the method of manufacturing the pulp fiber for cellulose nanofiber forming from the pulp fiber contained in used sanitary goods. PROBLEM to be solved It is the method to manufacture the pulp fiber for cellulose nanofiber forming from the pulp fiber contained in used sanitary goods， Comprising: By supplying ozone containing gas to the processing tank 31 containing the process liquid containing the pulp fiber containing material 51 containing the used super-absorbent polymer and pulp fiber derived from sanitary goods， From the said pulp fiber， the pulp fiber for cellulose nanofiber forming which has the lignin content rate of 0.1 mass % or less is formed， The method characterized by including the pulp fiber-forming step for cellulose nanofiber forming.
