코일 보빈(57) 내에 수용하는 자성체 코어(47)를, 코일축 방향 X와 교차하는 코일축 교차 방향 Y를 따라 복수로 분할하고, 복수의 분할 자성체 코어(47a) 상호간에, 코일축 방향 X를 따라 연장되는 간극 C를 형성한다. 간극 C에는, 코어 베이스(51)로부터 상방으로 돌출되는 돌기(51a)를 삽입 배치하여 강성을 확보한다. 간극 C를 형성함으로써, 자성체 코어(47) 전체의 중량을 억제하면서, 코일의 코일축 교차 방향 Y의 폭을 넓게 확보한다. 코일 폭을 넓게 확보함으로써, 송전측 코일(11)과 수전측 코일(13)의 위치 정렬이 용이하게 된다.

    A magnetic core 47 to be housed in a coil bobbin 57 is split along a coil-axis intersecting direction Y into a plurality of split magnetic cores 47a, the coil-axis intersecting direction Y intersecting a coil axis direction X, and a clearance C extending along the coil axis direction X is provided between the plurality of split magnetic cores 47a. In each clearance C, a protrusion 51 a protruding upward from a core base 51 is inserted and arranged to ensure sufficient rigidity. Providing the clearances C reduces the entire weight of the magnetic core 47 and also ensures a large coil width in the coil-axis intersecting direction Y. By ensuring a large coil width, alignment between a power-transmission-side coil 11 and a power-reception-side coil 13 becomes easier.
