Abstract
Disclosed is a high-strength conductive film having excellent conductivity which can be applied in electronic devices, and which further reduces unevenness in conduction. The conductive film comprises modified fine cellulose having at least a carboxyl group and one type or two or more types of conductive substance. Further, the conductive film is formed by a process involving a step for oxidizing cellulose to prepare modified cellulose, a step for making finer the modified cellulose by dispersing the same in a dispersion medium to prepare modified fine cellulose, a step for mixing the modified fine cellulose and the conductive substance to prepare a dispersion liquid, and a step for drying the dispersion liquid to form a conductive film.
