The invention relates to a computer keyboard key structure, a thin film circuit is arranged on a substrate, the thin film circuit is composed of an upper circuit and a lower circuit, and the computer keyboard key structure is characterized in that a metal spring plate layer is arranged below a key cap layer which is composed of key caps, and a metal spring plate is correspondingly arranged below each key cap. A layer of light guide plate is also arranged between the key cap layer and the metal spring plate layer, and a light source is arranged at the side surface of the light guide plate. Thethin film circuit is arranged below the metal spring plate layer, and each metal spring plate is corresponding to a conductive point which is printed on the thin film circuit. The key cap layer adopts the ultraviolet curing one-step forming. The thin film circuit is the thin film circuit with a synclastic structure. The production process of a computer keyboard comprises the production of the keycaps by adopting the ultraviolet one-step forming mode, the production of the thin film circuit with the synclastic structure, the arrangement of the metal spring plates and the sequential adhesion of the key caps, the metal spring plates and the thin film circuit. The computer keyboard key structure has simple structure and convenient installation, and the whole assembly process can realize the mechanical production and improve the production efficiency.
