1. A wireless power receiving device for an electric vehicle, the wireless power receiving device comprising:
a wireless power receiving coil configured to receive wireless power transmitted from the outside;
a coil support member configured to prevent movement of the wireless power receiving coil by fixing the wireless power receiving coil through a position fixing means formed at a position corresponding to the wireless power receiving coil;
a ferrite core including a plurality of ferrite block bodies having predetermined areas and disposed on one surface of the coil support member to be adjacent to each other; and
a plate-shaped metal plate provided with a predetermined area, disposed to cover one surface of the ferrite core, and provided as a metal plate to shield an electromagnetic wave,
wherein the ferrite core serves as a main shielding material to shield the magnetic field generated from the wireless power receiving coil, and
wherein the coil support member is a composite in which the magnetic substance is dispersed in a polymer so as to serve as an auxiliary shielding material that assists the ferrite core and shields a magnetic field.
