The present invention is a coil (1) for noncontact power supply that is provided with a winding (31) and a core (41) forming a part of a loop magnetic path linked with the winding and is used in a power supply side device and/or a power receiving side device of a noncontact power supply system (9), wherein the core is constituted of three or more core units joined in a series, and the core units include one or more linking core units (E shape core 5) for linking with the winding and two non-linking core units (L shape core 6) that are disposed respectively on the two ends of the one or more linking core units in the direction of joining and do not link with the winding. Thus, because the non-linking core units have a magnetic shielding effect so that magnetic flux generated by the winding does not leak to the outside even though the contribution of the non-linking core units to electromagnetic coupling is small, it is possible to provide a coil for noncontact power supply wherein increases in magnetic flux leakage are suppressed. |
