An electronic device including a first housing, a second housing and a pivot structure is provided. The pivot structure includes a pivot shaft, a sliding component and a supporting component. The pivot shaft is pivoted on the first housing. The sliding component is disposed on the second housing. One end of the sliding component sleeves the pivot shaft, such that the second housing rotates relative to the first housing. The supporting component has a first end and a second end. The first end is pivoted to the first housing. When the second housing rotates relative to the first housing, the supporting component provides a supporting force to the second housing.
