There is provided a use of a material comprising fibers as an oxygen barrier, wherein the fibers comprise native cellulose and dialcohol cellulose. There is also provided a material comprising fibers and having a density of at least 1200 kg/m.sup.3, wherein the fibers comprise native cellulose and dialcohol cellulose and the oxygen permeability of the material according to ASTM D3985 is below 30 ml.Math.?m/(m.sup.2.Math.kPa.Math.24 h) at 23? C. and 80% relative humidity.

Disclosed is a material that effectively utilizes natural resources and is friendly to the environment as a whole. Specifically, disclosed is a barrier material that has excellent strength and excellent affinity and adhesion to a paper base due to an interaction with paper fibers and that gives sufficient barrier properties even in the form of a thin film. A laminated body (100) includes, on at least one surface of a base (1) made of paper, a fiber layer (2) containing fine cellulose fibers each having a fiber diameter of 1 nm or more and 10 m or less. In particular, the fine cellulose fibers preferably have a fiber diameter of 1 nm or more and 30 nm or less.
