The invention discloses a method for forming a circuit on a base plate of a key. According to the method, a conductor slice element having the circuit is fixed on a base plate. Or the circuit is formed on the base plate by means of chemical plating, wherein the circuit is formed once by chemical plating or a semi-finished circuit is formed firstly and then the semi-finished circuit is trimmed by laser engraving to form the circuit. According to the invention, the circuit is formed directly on the base plate and the base plate and the circuit are combined; and the base plate can be used as a substrate of the circuit, so that the functions of the circuit board are realized based on the structure and thus the height of the key is reduced. 本发明揭露种于按键的底板上形成电路的方法。该方法可将具有该电路的导体薄片件，固定于该底板上而实现。该方法亦可利用化学镀方式在该底板上形成该电路而实现，其中该化学镀方式可次形成该电路，或是先形成半成品电路，再以雷射雕刻修剪该半成品电路以形成该电路。本发明直接于该底板上形成该电路，该底板与该电路结合，该底板可作为该电路的基板，使得整体结构亦可发挥电路板的功能，进而减少按键的高度。
