The present invention relates to an alicyclic polyimide resin composition including 100 parts by mass of an alicyclic polyimide resin (A) having a specific structure and from 1 to 13 parts by mass of a cyano-modified cyclic phenoxy phosphazene compound (B), and a thin-wall molded article formed of the alicyclic polyimide resin composition which is produced by casting a solution of the resin composition and then heating the cast solution. The present invention aims at obtaining an alicyclic polyimide resin composition that is imparted with a good flame retardancy without adding a halogen-based flame retardant, an antimony-based flame retardant, an inorganic metal hydrate, a phosphoric acid salt, etc., thereto, and also is excellent in transparency, heat resistance and insulating property, and a thin-wall molded article obtained from the resin composition.
