description The invention discloses a key and a keyboard comprising the same. The key comprises a base plate, a key cap, a lifting support device and a circuit board, wherein the base plate comprises a grounding arm part, the circuit board is arranged on the base plate, the circuit board forms an unfilled corner, a light emitting unit is arranged on the base plate at a position corresponding to the unfilled corner, the circuit board comprises an upper thin film layer, a lower thin film layer, a spacer layer, a first conductive layer and a second conductive layer, the first conductive layer is arranged between the lower thin film layer and the spacer layer, a part of the first conductive layer is not sheltered by the upper thin film layer and the spacer layer, the exposed part of the first conductive layer is adjacent to the unfilled corner, the second conductive layer is arranged between the upper thin film layer and the spacer layer so as to be in contact with the grounding arm part, and the second conductive layer is electrically connected with the first conductive layer by using a lead wire. The key and the keyboard can solve the problems of tedious assembly step and excessive production cost due to complex keyboard structure.
