The invention provides a manufacturing method of a segmented golden finger, which comprises the following steps: covering regions of a golden finger, except for a prefabricated segmented region and a to-be-gold-plated region, by adopting a first protection structure; gold-plating the prefabricated segmented region and the to-be-gold-plated region of the golden finger to form a gold-plated layer; and removing the gold-plated layer on the prefabricated segmented region. By adopting the first protection structure for covering the regions of the golden finger, except for the prefabricated segmented region and the to-be-gold-plated region, when the to-be-gold-plated region of the golden finger is gold-plated, the prefabricated segmented region can also be gold-plated, and then the gold-plated layer on the prefabricated segmented region is removed, so that in a gold-plating process, the prefabricated segmented region does not need to be covered by adopting the protection structure so as to avoid the phenomenon of gold infiltration caused by adopting the protection structure in the prior art to cover the prefabricated segmented region of the golden finger to directly obtain the segmented golden finger, and further avoid the condition of unstable performance of the golden finger caused by the phenomenon of gold infiltration.
