Embodiments of this application provide an electronic device, in which a heat sink in the electronic device is multiplexed as a heat dissipation component and a radiator of an antenna. The heat sink provided by the embodiments of this application can be used as a heat dissipation component to distribute heat evenly, such as to cool down an overheated electronic element. In addition, the heat sink can be used as a radiator of an antenna to form an antenna unit with a feed unit and generate radiation to the outside. The heat sink in a first region can be used as a main radiator of the antenna unit to meet the demand for the number of antennas in a 5G wireless communication system, and can also be applied to other communication systems.
