The key structure comprises a key cap, a supporting assembly and a bottom plate, the bottom plate comprises a thin film circuit board, the two ends of the supporting assembly are movably connected to the bottom plate and the key cap respectively, the supporting assembly comprises a frustum-shaped elastic body, and the elastic body is arranged between the thin film circuit board and the key cap. The elastic body stores energy when the key cap is pressed down and enables the key cap to reset when the key cap is loosened. When the upper bottom of the elastic body abuts against the thin film circuit board on the bottom plate, the contact part of the thin film circuit board is triggered. The back surface of the key cap is provided with the first avoiding groove, and when the elastic body is compressed and deformed, the upward protruding part of the elastic body can be accommodated in the first avoiding groove, so that fa
