An electronic device includes an operation body, a frame and an antenna. The frame encloses a lateral side of the operation body. The antenna is disposed within the frame, and partially exposed outside the frame. The antenna is electrically connected with the operation body to provide a wireless communication function. A wireless communication interference source is disposed within the operation body, or the operation body contains a metallic material. Since the operation body is enclosed by the frame, the frame can protect operation body and prevent collision of the operation body. Moreover, since the antenna is located outside the operation body, the antenna is away from the interference source that is disposed within the operation body. Consequently, the wireless communication efficiency is enhanced, and the inner space of the operation body is saved.
