높은 임피던스를 갖는 공통 모드 초크 코일을 구비한 전자 부품 및 그 제조 방법을 제공하는 것이다. 자성체 기판(12a)은, 주면(S1, S2)을 접속하는 능선이 절결부(Ca 내지 Cd)에 의해 절결된 형상을 이루고 있다. 적층체(14)는, 절결부(Ca 내지 Cd)와 겹치는 코너(C1 내지 C4)를 갖는다. 코일(L1)은, 코일부(20)의 양단부에 접속되고, 또한, 코너(C1, C2)로 인출되어 있는 인출부(21a, 21b, 22a 내지 22c)를 포함하고 있다. 코일(L2)은, 코일(L1)과 함께 공통 모드 초크 코일을 구성하고, 코일부(25)의 양단부에 접속되고, 또한, 코너(C3, C4)로 인출되어 있는 인출부(26, 27a 내지 27d)를 포함하고 있다. 접속부(16a 내지 16d)는, 외부 전극(15a 내지 15d)과 인출부(21b, 22c, 26, 27d)를 접속하고, 절결부(Ca 내지 Cd)에 설치되어 있다. A magnetic substrate has such a shape that ridges extending between principal surfaces are cut away by cutout portions. A multilayer body has corners arranged so as to overlap the cutout portions. A coil includes lead portions which are connected with both ends of a coil portion and which are drawn out to the corners. A coil is combined with the coil to constitute a common mode choke coil and includes lead portions which are connected with both ends of a coil portion and which are drawn out to the corners. Connecting portions connect external electrodes to the lead portions and are provided at the cutout portion.
