<P>PROBLEM TO BE SOLVED: To provide a gas-barrier material from which a film or the like for suppressing the permeation of various gases such as water vapor, oxygen, carbon dioxide and nitrogen is obtained, and to provide a method for producing the same. <P>SOLUTION: The method of manufacturing the film-like formed body includes: a step of forming the film-like material on a substrate or a base material using a suspension containing cellulose fiber; a step of sticking a cross-linking agent aqueous solution having a reactive functional group to the film like material; and a step of cross-linking after that. The cellulose fiber contains one having an average fiber diameter of 200 nm or less, wherein cellulose that constitutes the cellulose fibers has a carboxyl group in content of 0.1 to 2 mmol/g. <P>COPYRIGHT: (C)2010,JPO&INPIT |
