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.

Electronic device including antenna member for wireless charging

An extrusion apparatus and a method for manufacturing an aluminum capillary tube using the same are provided. The extrusion apparatus includes a container, a housing mold provided on one side of the container and including a plurality of dies formed with a plurality of holes, and a ram pressing an aluminum billet accommodated in the container in a direction from another side to the one side of the container so that the aluminum billet accommodated in the container is extruded into a plurality of aluminum capillary tubes having cross-sectional shapes corresponding to the plurality of holes, and the number of the plurality of holes is determined based on an inner diameter of the container and a diameter of each of the plurality of holes.
