PROBLEM TO BE SOLVED: To provide a method for producing a pulp fiber raw material suitable as a cellulose raw material. SOLUTION: A method for producing pulp fiber raw material as a cellulose raw material from pulp fiber to be treated includes an ozone treatment step S36 of supplying ozone-containing gas to a treatment tank that contains a treatment liquid containing a pulp fiber matter containing a pulp fiber to be treated， so that an ozone-treated pulp fiber is formed from the pulp fiber to be treated， and an alkaline treatment step S39 of treating the ozone-treated pulp fiber with an alkaline aqueous solution， so that a pulp fiber material containing a hemicellulose of less than 8.0 mass% is formed.
