PURPOSE: To prepare efficiently an electrically conductive film of very thin thickness of 15μm or less, by coating a plastic film having a high releasing effect with a conductive composition, and peeling the coated layer from the plastic film.

CONSTITUTION: An electrically conductive film of a very high thickness whose thickness is 15μm or less can be easily prepared by coating a film having a high releasing effect such as, polyethylene film, a polypropylene film or a fluoro resin film with a conductive composition and peeling the coated layer from these plastic films, even when a conventional coating apparatus is used. The conductive film thus obtained can be used for a packaging bag for electronic parts as an anti-electrostatic material, and also used for a base material for electro-conductive heat-transfer-printing-type ribbons.
