Zusammenfassung:	Embodiments of this application provide a rear cover of an electronic device, an electronic device, and an air tightness detection system of an electronic device. The electronic device may include a mobile or fixed terminal having waterproof performance such as a mobile phone, a tablet computer, or a notebook computer. The rear cover includes a body portion and a structure layer fixed to a rear surface of the body portion. A smooth detection plane is formed on a rear surface of the structure layer, and a rear end of a balance channel of the rear cover is located within the detection plane, thereby resolving the problem that the material of the rear cover affects air tightness detection on the electronic device.
