Paint, which adheres well to the surface treatment layer, can provide additional corrosion protection.

Abstract: An electroplating base includes a separate electrically conductive section isolated from an electrically conductive section. An electrically conductive connecting pattern connects the separate electrically conductive section to the electrically conductive section. Electroplating allows establishment of electroplating films on the electrically conductive section and the separate electrically conductive section. A non-conductive path extends in the electroplating base from a point of a non-conductive section to a point of the non-conductive section. The ends of the non-conductive path are connected to the non-conductive section, so that generation of electroplating films is reliably avoided at the ends of the non-conductive path. The obtained non-conductive section and non-conductive path serve to reliably insulate the electroplating film on the electrically conductive section and the electroplating film on the separate electrically conductive section from each other.

The depression of the substrate can easily be formed based on etching process, for example. A flat surface can be established at the tip end of the light waveguide based on the etching process. Loss of light can be prevented to the uttermost at the contact with fiber optics connected to the light waveguide.
