PROBLEM TO BE SOLVED: To provide a film of polypyrroles, having practicable high thermoelectric figure of merit (ZT) equal to a conventional organic thermoelectric material, and capable of exhibiting high weather resistance. SOLUTION: This film of the polypyrroles is characterized in that the film has a thin thickness such as 0.42-2,000 nm thickness, and a crystallinity satisfying the formula: Imax /W1/2 >=0.5 (wherein, Imax is the maximum diffracted intensity; and W1/2 is the half value width of the diffraction peak) as X-ray diffraction spectrum. The method for producing the film and the thermoelectric material comprising the film are also provided. |
