摘要： Provided is a wireless power transfer antenna core. In the wireless power transfer antenna core according to an exemplary embodiment of the present invention, a conductive member configured to serve as an antenna for transmitting or receiving wireless power is wound multiple times along a longitudinal direction. The wireless power transfer antenna core is made of a magnetic body and comprises: a first portion having a first cross-sectional area; and a second portion extending with a predetermined length from an end of the first portion and second cross-sectional area that is relatively larger than the first cross-sectional area, wherein the conductive member is wound multiple times on the first portion.
