Electronic device and fixing structure thereof

Disclosed are an electronic device and a fixing structure thereof. The fixing structure comprises a casing made of a metal material and a fixing seat. The casing is provided with a bearing plane, the fixing seat is arranged on the casing, the fixing seat is provided with a first contact end and a second contact end which are opposite, the vertical distance between the first contact end and the bearing plane is larger than that between the second contact end and the bearing plane, a wireless transmission device is arranged on the fixing seat and is in contact with the first contact end and the second contact end, and thereby the vertical distance between an antenna end of the wireless transmission device and the bearing plane is larger than that between a fixed end of the wireless transmission device and the bearing plane. Accordingly, a large distance between the antenna end and the casing can be maintained, and the antenna end can be prevented from being disturbed by the metal material of the casing.
