A magnetic core (47) housed inside a coil bobbin (57) is split into a plurality, along a coil axis-intersecting direction (Y) that intersects a coil axis direction (X), and gaps (C) extending along the coil axis direction (X) are provided between each of the plurality of split magnetic cores (47a). Protrusions (51a) that protrude upwards from a core base (51) are arranged inserted into the gaps (C) and ensure rigidity. As a result of providing the gaps (C), the entire weight of the magnetic core (47) is reduced and a greater coil width is maintained in the coil axis-intersecting direction (Y). By ensuring wider coil gaps, the positioning of a power transmission-side coil (11) and a power reception-side coil (13) becomes easier. |
