ABSTRACT OF THE DISCLOSURE An aromatic polysulfone resin composition with excellent plating characteristics comprising: (A) 50 to 90% by weight of an aromatic polysulfone, (B) 3 to 40% by weight of wollastonite of which 90% by weight or more of the total amount have a particle size smaller than 300 meshes, and (C) 3 to 30% by weight of an alkaline earth metal carbonate is disclosed. This aromatic polysulfone resin composition has excellent mechanical properties, thermal properties (in terms of thermal deformation temperature and linear thermal expansion coefficient), dimensional stability, thermal stability during processing and surface smoothness and also shows excellent plating characteristics in a wide range of plating conditions (etching conditions). By using this aromatic polysulfone resin composition, it is possible to easily obtain a printed circuit board having a desired configuration by means of injection molding, and it becomes possible to form the circuits with a fine line width.
