Beschreibung
Zusammenfassung:	The present invention provides a resin composition containing (C) carbon fibers of 5 to 75 parts by mass relative to 100 parts by mass of a polyamide resin, which comprises (A) a polyamide resin of 90 to 50 mass% and (B) a polyamide resin of 10 to 50 mass% relative to 100 mass% of the total of the component (A) and the component (B), wherein the component (A) has 7 or more carbon atoms per one amide group and does not have an aromatic ring, and the component (B) has an aromatic ring and shows crystallinity. The present invention provides a resin composition, a pellet thereof and a molded article thereof, wherein the resin composition has excellent moldability, less degradation of rigidity and strength when absorbing water, which is the defect of the polyamide resin, and excellent appearance.
