A non-contact power feeding coil provided with a coil; and a core that forms a part of a circulating magnetic path that is interlinked to the coil, and used in at least one of a power feeding-side device and a power receiving-side device of a non-contact power feeding system, in which the core is configured to connect three or more core units in one row, and the core units include one or more interlinked core units that are interlinked to the coil and two non-interlinked core units that are not interlinked to the coil respectively disposed on both ends in the connection direction of the one or more interlinked core units. Thereby, it is possible to provide a non-contact power feeding coil that suppresses an increase in leakage flux.
