Provided is a riveted metal middle frame including a middle plate and a border frame riveted to the middle plate. The middle plate is made of aluminum alloy, and the periphery of the middle plate is convexly provided with convex edge. The border frame includes members connected end to end in sequence. The members are made of metal material with hardness not less than aluminum alloy, and are riveted to the periphery of the middle plate; and the inner sides of the members are respectively provided with slots for connecting the convex edge. The convex edge is riveted to the slot by press-fitting the border frame. Meanwhile, an electronic device including the above-described riveted metal middle frame is also provided. The beneficial effects are that the middle plate and the border frame are riveted together by press-fitting deformation, thereby improving production efficiency and reducing manufacturing cost.
