  Provided is a method for producing a π-conjugated polymer capable of suppressing an increase in dark current of an organic photoelectric conversion element even if the method includes a purification step including heating. A method for producing a π-conjugated polymer includes: step (I) of heating and dissolving a crude π-conjugated polymer in a solvent to obtain a polymer solution; and step (II) of precipitating a π-conjugated polymer from the polymer solution. In step (I), the content of peroxide in the solvent is 0.1% or less in terms of a relative area ratio measured by high-performance liquid chromatography, and the electron spin concentration of the π-conjugated polymer is 30 × 1016 Spin/g or less and/or 2.5 times or less the electron spin concentration of the crude π-conjugated polymer.
