Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a wireless power feeding device capable of easily increasing an allowable amount of positional deviation between a power feeding unit and a power receiving unit.SOLUTION: A wireless power feeding device includes: two primary coils 11 and 12; and a secondary coil 13 which is arranged so that the two primary coils 11 and 12 are interlinked with a magnetic flux 21 generated during energization of the two primary coils 11 and 12. The two primary coils 11 and 12 are arranged so that an angle formed by two planes S11 and S12 orthogonal to central axes A11 and A12 of the two primary coils 11 and 12 becomes 0 or more and less than 360 degrees.
