PROBLEM TO BE SOLVED: To provide a power feeding device for apparatuses capable of highly efficiently feeding power in non-contact with an apparatus.SOLUTION: The power feeding device for apparatuses comprises: a coupled resonator that includes a first resonator 10 including a first coil 11, and a second resonator 20 including a second coil 21 that is coaxially disposed facing the first coil 11 at a prescribed distant apart therefrom without being connected to the first coil 11 and in which, in a state where an alternating current is fed to the first coil 11, the first resonator 10 and the second resonator 20 are magnetically coupled and resonate； and a power supply 13 that feeds the alternating current to the first coil 11. The power feeding device feeds the power to an apparatus 100 disposed between the first coil 11 and the second coil 21 that are faced and disposed in the coupled resonator, via a third resonator 30 that is provided in the apparatus 100 and magnetically coupled with the coupled resonator.
