NON-CONTACT POWER RECEPTION DEVICE, VEHICLE COMPRISING SAME, NON-CONTACT POWER TRANSMISSION DEVICE, AND NON-CONTACT POWER TRANSMISSION SYSTEM

AC power having a power transmission frequency (f1) is transmitted from a resonant coil (140) in a power transmission device (100) to a resonant coil (210) in a power reception device (200). Moreover, communication is conducted between a communication device (170) in the power transmission device and a communication device (290) in the power reception device through wireless radio wave having a communication frequency (f2). The power transmission frequency (f1) and the communication frequency (f2) are determined in such a way that the relationship between the power transmission frequency (f1) and the communication frequency (f2) is a non-integer multiple.
