A portable information device includes a first chassis member, a second chassis member, a hinge mechanism, a display and a bezel member provided to bridge an outer peripheral edge portion of the display and an outer peripheral edge portion of the first and second chassis members. The bezel member is arranged farther away from the inner surfaces of the first and second chassis members than a rotation center of the hinge mechanism. The bezel member has a buffer portion at least at a position overlapping a bent portion of the display. The buffer portion can absorb compressive force F applied thereto as the first and the second chassis members are folded from a flat opened state.
