A supporter includes a connecting body, a pair of supporting plates, and a pair of supporting arms. The pair of supporting plates is rotatably connected to the connecting body. The pair of supporting arms is rotatably connected to the supporting plates. When the supporter is in an open state, the pair of supporting arms are rotated to rest against each other. The pair of supporting arms and the corresponding supporting plates respectively form an angle therebetween so that the supporting arms and corresponding supporting plates are positioned in a manner to cooperatively support an electronic device. When the supporter is in a close state, the pair of supporting arms are received in the receiving chambers.
