Abstract
A keyboard device includes a substrate, a touch panel module, a cover plate, a cover layer, an elastic layer, and an adhesive layer. The touch panel module is disposed on a top surface of the substrate and includes a circuit board. The cover plate covers the top surface and includes an avoidance hole defined through an upper surface and a lower surface of the cover plate. The cover layer covers the upper surface and includes a through hole. The through hole corresponds to the avoidance hole. The elastic layer is in the through hole and includes a peripheral portion. The peripheral portion is seamlessly connected to a hole edge of the through hole. The adhesive layer is adhered between a first inner surface of the cover layer and the upper surface and adhered between a second inner surface of the elastic layer and the circuit board.
