A keypad assembly includes a keypad, a fixing bracket, and at least one fixing member. The fixing member fixes the keypad to the fixing bracket, and the fixing bracket includes two support portions, a fixing portion, two connecting portions and at least two resilient portions. The resilient portions interconnect the support portions and the fixing portions. Opposite ends of each connecting portion interconnect the two support portions, such that the two connecting portions and the two support portions cooperatively form a frame. The fixing portion is located on a middle portion of the frame. The keycap is fixed on the fixing portion. The resilient portions elastically deform to provide elastic restoring force to the keycap.
