Abstract
A keyboard device includes a circuit board and plural key structures. Each key structure includes a keycap, a hinge element and a base. The hinge element includes a first lateral wing part, a second lateral wing part and a bendable part. The first lateral wing part is connected between the keycap and the base. The second lateral wing part is connected between the keycap and the base. The bendable part is connected between the first lateral wing part and the second lateral wing part. The bendable part is thinner than the first lateral wing part and the second lateral wing part. While the keycap is moved upwardly or downwardly relative to the base, a bending angle of the hinge element and a relative position between the first base shaft and the first receiving hole are changed.
