The torsion element is disposed at the hinge cover. The bracket is disposed at a side of the torsion element. The fixing element is fixed at one of the torsion element and the bracket by a fixing portion. The shaft is disposed at the hinge cover and passed through the torsion element, the bracket and the fixing element so that one of the torsion element and the bracket is adapted to rotate with the fixing element in relative to another one of the torsion element and the bracket through the shaft as an axle center. An electronic device including the aforementioned hinge structure is also provided. ## Claims ### Claim 1 A hinge structure, comprising: a torsion element, having a first through portion; a shaft, passing through the first through portion;
