A polyamic acid that includes a polyamic acid (A) obtained by reacting a tetracarboxylic anhydride containing 3,3',4,4'-biphenyltetracarboxylic dianhydride with a diamine compound containing 4,4'-oxydianiline, a conductivity-imparting agent (B), and an imidization accelerator (C) and in which the conductivity-imparting agent is dispersed is used as a coating liquid; the coating liquid is applied onto a support; the obtained coating film is dried and imidized; and an electrically conductive polyimide film having a desired electric resistivity and good mechanical properties is consequently produced with good productivity. |
