A sliding electronic device includes a first component, a second component, a connecting element and a torsion element. The second component faces the first component. The connecting element is disposed between the first component and the second component, and has a first end and a second end, wherein the first end is rotatably disposed within the first component, and the second end is movably disposed within the second component. The torsion element connecting the first component to the connecting element is for providing torque to drive the connecting element. When a relative movement between the first component and the second component is generated under an applied force, the connecting element and the torsion element cause the second component to move between a close location and an open location on the first component.
