description	Disclosed in the invention is a key structure comprising a base plate, a switch circuit board, a key cap, and a frame. The key cap has a magnetic element arranged at the edge of the key cap. The frame has a magnetic coating layer arranged at the frame edge and is below the magnetic element. When the key cap is touched and pressed, the key cap moves and the switch circuit board is triggered to generate a key signal. When the key cap is not touched and pressed, the key cap moves towards the magnetic element based on the magnetic force generated by the magnetic element. Therefore, the key structure can be operated normally without the need of elastic rubber.
