Zusammenfassung:	To provide: a polyamide resin composition which has few black spot foreign materials and is sufficiently improved in mechanical properties such as the flexural modulus, the tensile modulus and the linear expansion coefficient; and a method for producing the same.SOLUTION: A polyamide resin composition contains 0.01-200 pts.mass of cellulose fibers per 100 pts.mass of a polyamide resin. The number of pellets containing black spot foreign materials per 100 pellets comprising the polyamide resin composition is 10 or less. The polyamide resin contains as a monomer component a monomer that is in a liquid state at a polymerization temperature.SELECTED DRAWING: None 【課題】黒点異物が少なく、曲げ弾性率、引張弾性率および線膨張係数等の機械的特性が十分に向上しているポリアミド樹脂組成物、およびその製造方法を提供する。【解決手段】ポリアミド樹脂１００質量部に対してセルロース繊維０．０１～２００質量部を含有するポリアミド樹脂組成物であって、前記ポリアミド樹脂組成物からなるペレット１００個当たりの黒点異物含有ペレットの個数が１０個以下であるポリアミド樹脂組成物、および、前記ポリアミド樹脂が重合温度で液体状態のモノマーをモノマー成分として含む、ポリアミド樹脂組成物。【選択図】なし
