An embodiment of the present invention relates to a wearable electronic device, relates to the field of wearable devices, and mainly aims to solve the technical problem of relatively poor wireless communication quality of a smart swatch. The following major technical scheme is adopted: a wearable electronic device comprises a wearing-side shell, a communication-side shell opposite to the wearing-side shell, and a circuit chip board. An accommodation space is formed between the wearing-side shell and the communication-side shell. A metal region of the communication-side shell serves as a metal antenna, and the metal antenna has a feeder terminal and a ground terminal. The circuit chip board is disposed in the accommodation space and comprises a communication module, an antenna feed pin electrically connected to the communication module, and an antenna ground pin electrically connected to the communication module, wherein the antenna feed pin is electrically connected to the feeder terminal of the metal antenna, and the antenna ground pin is electrically connected to the ground terminal of the metal antenna. The wearing-side shell is a metal shell. The wearable electronic device has relatively high wireless communication capability in use.
