PURPOSE:To obtain a new compound film which is especially excellent in the uniformity of conductivity by forming a conductive macromolecular compound layer in a macromolecular film containing fine particles of inorganic compound in a dispersed state. CONSTITUTION:A conductive macromolecular compound layer is formed in a macromolecular film containing inorganic fine particles in a dispersed state. Fine particles of nonconducting inorganic substance and macromolecular substance are kneaded together and molded to form a film. As a nonconducting inorganic substance, there are silicon oxide, calcium carbonate or basic magnesium carbonate. According to a purpose, one of these inorganic substance is selected and mixed uniformly with a macromolecular substance, and a film of a characteristic corresponding to the kind of an inorganic substance is obtained. The film has high uniform conductivity on the whole area; therefore it can be applied to a wide range of usage as a conductive film.
