Claim 12:
13. The wireless charging antenna of claim 12, wherein the NFC antenna includes:
a third conductive pattern corresponding to an area where current spirally flows toward the inside of the NFC antenna, among areas configured to form the NFC antenna; and
a fourth conductive pattern corresponding to an area where the current spirally flows toward the outside of the NFC antenna, among the areas configured to form the NFC antenna, wherein the fourth conductive pattern is disposed parallel to the third conductive pattern on a side of the third conductive pattern on the same plane,
wherein the third conductive pattern and the fourth conductive pattern are formed of a plurality of layers including a third layer and a fourth layer, and
wherein in a third area where part of the third conductive pattern and part of the fourth conductive pattern intersect each other, the third conductive pattern does not include the third layer, and the fourth conductive pattern does not include the fourth layer.
