Abstract: Embodiments of this application provide a middle frame, a rear cover, and fabrication methods thereof, and an electronic device. The electronic device may include a mobile or fixed terminal with a frame or a housing, such as a mobile phone, a tablet computer, a notebook computer, an ultra-mobile personal computer (UMPC), a handheld computer, a walkie-talkie, a netbook, a POS terminal, a personal digital assistant (PDA), an event data recorder, a wearable device, a virtual reality device, a wireless USB flash drive, a Bluetooth speaker/headset, or a vehicle-mounted device. Ceramics and fiber reinforced composite are used to form frames of a rear cover and a middle frame, to reduce thicknesses of a ceramic outer housing and a ceramic outer frame, thereby reducing a weight of the electronic device.
