Abstract

An electronic device is provided. The electronic device includes a first circuit board, an antenna member disposed to face one surface of the first circuit board, an electronic module disposed between the first circuit board and the antenna member and including a plurality of contact protrusions disposed to face the antenna member, and a plurality of contact members disposed on the antenna member and configured to electrically contact one of the plurality of contact protrusions. As the antenna member generates an induced current in reaction to an external electrical signal or an external electromagnetic field, the electronic module may be configured to supply power using the induced current generated by the antenna member.
