PROBLEM TO BE SOLVED: To solve a problem wherein conventional conductive polymers lower their conductivities by heat and the like, and are difficult to stably maintain the conductivities for long periods, and, especially, polypyrrole-based polymers are easily oxidized, remarkably reduce the electric conductivities, do always not have sufficient performances, and have been required to be improved. SOLUTION: The heat-resistant conjugated pyrrole copolymer film obtained by reacting pyrrole with a formyl (-CHO) group-containing monomer represented by general formula (1) (wherein, R<SB>1</SB>and R<SB>2</SB>are each independently H, a 1-6C linear or branched saturated or unsaturated hydrocarbon group, OH, a halogen atom, nitro, cyano, trihalomethyl, phenyl or substituted phenyl; X is NH or O) in a pyrrole: formyl (-CHO) group-containing monomer molar ratio of 0.9:0.1 to 0.1:0.9 in the presence of an acidic catalyst in a molar amount of 2.5 to 5.0 times the total moles of both the monomers at -10°C to 75°C, is characterized by having structural units of general formula (2) [(n) is an integer of≥1] in at least one structural portion of the copolymer.
