The present invention relates to a feeding apparatus for an electric vehicle capable of supplying a higher capacity of electric power than an existing feeding apparatus by changing a configuration method and arrangement of a feeding coil for a feeding apparatus of an electric vehicle. The feeding apparatus comprises: a feeding core part including a plurality of substrates embedded along a travelling direction on a road to be spaced apart from each other so as to prevent flux leakage, and a column formed at the center of the substrate; and first and second feeding lines for forming a magnetic field, wherein the first and second feeding lines are disposed in the feeding core part, and the first feeding line and the second feeding line conduct electric currents in opposite directions to each other. 본 발명은 전기자동차의 급전장치용 급전코일의 구성방법 및 배치를 변경함으로써 기존의 급전장치보다 고용량의 전력을 공급할 수 있는 전기자동차용 급전장치에 관한 것으로, 도로 진행방향을 따라 다수개가 이격되게 매설되어 자속누설을 방지하는 기판과 상기 기판 중앙에 형성된 기둥을 포함하는 급전코어부 및 자기장을 형성하도록 하는 제1,2 급전선;을 포함하되, 상기 제1,2 급전선은 상기 급전코어부에 배치되고 상기 제1 급전선과 제2 급전선은 서로 반대 방향으로 전류가 흐르는 것을 특징으로 하는 전기자동차용 급전장치를 제공한다.
