NOVELTY - Charge transport film is formed through subjecting a coating film comprising at least one charge transporting agent to an atmospheric pressure plasma treatment, where electron transfer between the charge transport film and a substance that contacts with the charge transport film is promoted.    USE - The charge transport film is useful for producing light emitting element and photoelectric conversion element (all claimed).    ADVANTAGE - The invention provides charge transport film which exhibits excellent charge transportability and stability over time; and provides production method with good productivity.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are:    (1) a method for producing charge transport film comprising forming a coating film including at least one charge transporting agent, and applying, to the formed coating film, plasma generated using an atmospheric pressure plasma generating apparatus, in an inert gas flow; or a method for producing charge transport film comprising forming a coating film including at least one charge transporting agent, and applying, to the formed coating film, an inert gas plasma generated using an atmospheric pressure plasma generating apparatus in which electricity is conducted via a pulse control element;    (2) a light emitting element comprising the charge transport film;    (3) a photoelectric conversion element comprising the charge transport film; and    (4) a compound comprising R1R2C=C(R3)-(C=O)-O-L-Ar1-(C=O)-O-Ar2-R4.    Ar1 and Ar2=each independently represent an arylene group;    L=a divalent linking group selected from alkylene groups having from 1 to 22 carbon atoms, arylene groups having from 6 to 22 carbon atoms, and -O-, or a divalent linking group obtained by combining two or more linking groups selected from alkylene groups having from 1 to 22 carbon atoms, arylene groups having from 6 to 22 carbon atoms, and -O-; and    R1, R2, R3 and R4=each independently represent a hydrogen atom or an alkyl group having 1 to 8 carbon atoms.
