Pulp fiber containing little ash is effectively recovered from a used sanitary product containing the pulp fiber and a polymer absorbent. The method according to the present invention comprises: a step for treating the used sanitary product with an ozone-containing gas and thus decomposing and removing at least a portion of the polymer absorbent in the used sanitary product; and a step for stirring the used sanitary product， that has been treated with the ozone-containing gas， in water or an aqueous solution containing an antiseptic and thus decomposing the used sanitary product into constituents. If required， the method may further comprise a step for separating the pulp fiber from the decomposition product obtained by the decomposition step.
