Zusammenfassung:	The present invention relates to polyamide multifilament fiber for a tire cord and a tire cord comprising same, the polyamide multifilament fiber comprising: a bio-based polyamide; and a copper compound which is added so that the concentration of copper is 30-300 ppm with respect to the polyamide, wherein the sulfuric-acid relative viscosity of yarn is 2.5-5, the yarn strength is 8 g/d or more, and the yarn orientation is 50x10-3 or more. According to the present invention, polyamide multifilament fiber for a tire cord, a tire cord, and a tire can be obtained, the polyamide multifilament fiber being eco-friendly by using a bio-based material, and having excellent strength and shape stability. La présente invention concerne une fibre multifilament de polyamide pour un câble pour pneu et un câble pour pneu comprenant ladite fibre, la fibre multifilament de polyamide comprenant : un polyamide biosourcé ; et un composé de cuivre qui est ajouté de telle sorte que la concentration de cuivre est de 30 à 300 ppm par rapport au polyamide, la viscosité relative de l'acide sulfurique du fil étant de 2,5 à 5, la résistance du fil étant égale ou supérieure à 8 g/d, et l'orientation du fil étant de 50x10-3. Selon la présente invention, une fibre de polyamide pour câble pour pneu, un câble pour pneu et un pneu peuvent être obtenus, la fibre multifilament de polyamide étant respectueuse de l'environnement par l'utilisation d'un matériau biosourcé, et présentant une excellente résistance et stabilité de forme. 본 발명은 바이오-기반 폴리아미드(bio-based polyamide)와 상기 폴리아미드에 대하여 구리 농도가 30~300 ppm이 되도록 첨가되는 구리 화합물을 포함하고, 원사 황산 상대점도 2.5~5, 원사 강도 8 g/d 이상, 원사 배향도 50x10-3 이상인 것을 특징으로 하는 타이어 코드용 폴리아미드 멀티필라멘트 섬유 및 이를 포함하는 타이어 코드에 관한 것으로, 본 발명에 의하면 바이오-기반 재료를 이용하여 친환경적이면서도, 강도 및 형태안정성이 우수한 타이어 코드용 폴리아미드 멀티필라멘트 섬유, 타이어 코드 및 타이어를 얻을 수 있다.
