Cellulose fiber containing metal ion， hygienic thin paper and absorbent article using the same

Provided is a cellulose oxide fiber having a sufficient deodorizing function， a hygiene thin paper using the same， and an absorbent article. Ag， Au， Pt， Pd， Ni， Mn， Fe， Ti， Al， Zn and Cu of cellulose oxide fibers having a carboxyl group or carboxylate group amount of 0.1 to 2.0 mmol/g with respect to the dry mass of the cellulose oxide fibers It is a metal ion-containing cellulose fiber that contains ions of at least one metal element selected from the group， and has a Canadian standard freeness of 30-400 ml of metal ion-containing cellulose fibers. [Problem] To provide an oxidized cellulose fiber having an adequate deodorizing function， a sanitary thin paper using same， and an absorbent article. [Solution] A metal-ion-containing cellulose fiber having a Canadian Standard Freeness of 30-400 ml， the metal-ion-containing cellulose fiber containing one or more metal-element ions selected from the group consisting of Ag， Au， Pt， Pd， Ni， Mn， Fe， Ti， Al， Zn， and Cu， in an oxidized cellulose fiber in which the amount of a carboxyl group or a carboxylate group is 0.1-2.0 mmol/g in relation to the absolute mass of the oxidized cellulose fiber.
