A wireless charging device for an electric vehicle of the present invention is characterized by including: a power conversion part that converts direct current voltage into alternating current voltage; a power transmission part that generates a rotating magnetic field for power transmission using power supplied from the power conversion part; a processor that controls the power conversion part to convert the direct current voltage into alternating current voltage; and a magnetic field line leakage prevention part that prevents the magnetic field lines generated by the power transmission part from leaking to the outside. Thus, the present invention can provide the wireless charging device for an electric vehicle that generates an orthogonal or rotating magnetic field through differential coils arranged in an orthogonal stacked structure, thereby minimizing the proximity effect while transmitting large power or the same power at a high power density.
