In a keyboard device, multiple key units are assembled on a circuit board unit that includes a wiring board mounted on a substrate and provided with multiple electrical contacts. Each electrical contact is registered with a corresponding through hole in the substrate. In each key unit, a resilient support member has a closed upper portion that abuts against the key cap, and an open lower portion that extends into a corresponding through hole and that abuts against the wiring board. A conducting pad on the support member is spaced apart from the electrical contact in the corresponding through hole when the key cap is at a normal position, and pressing of the key cap results in deforming of the support member such that the conducting pad contacts electrically the electrical contact in the corresponding through hole.
