To obtain an aromatic polysulfone resin solution composition good in dispersion of an electroconductive carbon black and an aromatic polysulfone resin film using the composition and to provide a method for producing the film.

[1] This aromatic polysulfone resin solution composition comprises (A) an aromatic polysulfone resin, (B) the electroconductive carbon black, (C) a surfactant and a solvent in a weight ratio (A)/(B) of (A) to (B) of 1≤(A)/(B)≤40 and the maximum particle diameter of (B) is ≤3 μm. [2] The method for producing the aromatic polysulfone resin film comprises (1) casting the aromatic polysulfone resin solution composition [1] onto a support and forming a cast film containing the solvent and (2) evaporating the solvent from the cast film. [3] The aromatic polysulfone resin film is produced by the method for producing the aromatic polysulfone resin film [2].
