To provide a composite resin composition of an aromatic polyetheretherketoneketone that has improved rigidity and improved mechanical strength such as retention of strength at an elevated temperature or the like and has electrical properties such as conductivity and antistatic properties without impairing inherent properties such as heat resistance, chemical resistance and the like possessed by an aromatic polyetheretherketoneketone.

Rigidity and mechanical strength can be improved by adding a fibrous filler such as a glass fiber, a carbon fiber, a whisker or the like to the aromatic polyetheretherketoneketone. Particularly, the addition of a carbon nanotube as a fibrous filler can contribute to improved mechanical strength and electrical properties such as conductivity, antistatic properties and the like efficiently even though added in a small amount.
