Laminated body

A laminated body comprising:

• a substrate;
• an anchor layer on a surface of said substrate;
• and
• a cellulose fiber layer on said anchor layer, said cellulose fiber layer containing a cellulose fiber having carboxy groups, wherein
• said anchor layer contains a resin having at least one functional group selected from the group consisting of carboxy group, sulfonate group, amino group and hydroxyl group,
• wherein said cellulose fiber is oxidized cellulose in which said carboxy groups are introduced by an oxidation reaction and a content of said carboxy groups in said cellulose fiber is in the range of 0.1-5.5 mmol/g,
• wherein said cellulose fiber has a number average fiber diameter in the range of 0.001-0.200 μm, and
• wherein said anchor layer contains another resin having a carboxy group, and said carboxy group forms an ammonium salt or an amine salt.
