Various embodiments of the present invention relate to a wireless charging system of an electric two-wheeled vehicle. The present invention provides a wireless power transmission system which can be applied to an electric two-wheeled vehicle, wherein a separation distance between a power feeding device and a current collecting device is approximately 5 to 10 cm through a magnetic induction coupling method or a magnetic resonance method. For the above, the wireless charging system of a two-wheeled vehicle provided by various embodiments of the present invention includes: a two-wheeled vehicle holder which has a feeding inverter providing a high frequency power source for wireless charging and a feeding pad connected to the feeding inverter and converting and radiating a high frequency power source into a magnetic field; and the electric two-wheeled vehicle which has a current collecting pad installed in an area corresponding to the feeding pad of the two-wheeled vehicle holder, converting a magnetic field into high frequency AC power, and collecting the converted power, a rectifier connected to the current collecting pad and rectifying the high frequency AC power into DC power, a DC-DC converter connected to the rectifier and boosting or decompressing the DC power, and a battery connected to the DC-DC converter.
