A keyboard device includes a base plate, a key and a membrane circuit board. The key is connected with the base plate. The membrane circuit board is arranged between the key and the base plate. The base plate includes a connecting structure. The connecting structure is protruded upwardly and penetrated through the membrane circuit board. The key includes a keycap and a stabilizer bar. The stabilizer bar is pivotally coupled to the keycap. A hook part of the stabilizer bar is penetrated through a corresponding locking hole of the connecting structure. A film layer of the membrane circuit board includes an extension part. A gel layer is formed on the extension part. While the keycap is moved upwardly or downwardly relative to the base plate, the hook part of the stabilizer bar is moved on the gel layer.
