WIRELESS POWER TRANSMISSION DEVICE AND POWER RECEIVING DEVICE
First Claim
1. A wireless power transmission device that supplies power to a power receiving device including a second self-resonant coil having a winding structure in which a conductive wire is wound one turn or more perpendicularly to a second central axis, the wireless power transmission device comprising:
- a first self-resonant coil having the winding structure in which the conductive wire is wound one turn or more perpendicularly to a first central axis to supply the power to the second self-resonant coil that is not located on the first central axis; and
a third self-resonant coil having the winding structure in which the conductive wire is wound one turn or more perpendicularly to a third central axis that is not perpendicular to the first central axis and arranged on the first central axis.
