According to one embodiment, an electronic device includes: a main body; a display device including an inputting unit; a hinge mechanism that joints the main body and the display device; and a projection portion projecting from the main body. The hinge mechanism includes a turning axis that allows the display device to turn on a turning axial line arranged along one side of the display device, and a swinging axis that allows the display device to swing together with the turning axis on an axial line arranged in a direction that intersects with the turning axis. The projection portion interferes with the display device when the display device is swung on the swinging axis in the state that the display device is overlaid on the main body.
