Abstract: A method for manufacturing a base structure of lens-focusing mechanism first prepares a conductive member having at least two conductive parts, interconnection part, contacts and two conductive pins. The conductive parts have proximity ends separated and staggered to each other. An insulating base is formed by injection molding and encapsulates the conductive member wherein the conductive pins, the interconnection part and the contacts are exposed out of the insulating base. The interconnection part is cut and then a spring member is mounted to the insulating base and electrically connected to the conductive pins through the contacts. The present invention can solve the problem of difficulty in assembling conductive pins and connecting the spring member for the insulating base. The conductive member is arranged within the insulating base such that plastic material can be saved, the flatness, the stability and the anti-damage ability of base can be enhanced.
