Abstract
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 μm or less. In particular, the fine cellulose fibers preferably have a fiber diameter of 1 nm or more and 30 nm or less.
