A tablet computer (an example of an electronic device) includes a housing that contains an electric component, the housing including a fixed cover and a movable cover that constitute adjacent regions of a back surface of the housing, a hinge shaft that is disposed between a front edge of the fixed cover and a back edge of the movable cover that are adjacent to each other and supports the movable cover, and a first attachment plate that supports the movable cover rotatably about the back edge. The first attachment plate is movably attached to an inner chassis to which the fixed cover is fixed such that the hinge shaft is movable away from the front edge of the fixed cover.
