A substrate W having a non-plateable material portion 31 and a plateable material portion 32 formed on a surface thereof is prepared, and then, a catalyst is selectively imparted to the plateable material portion 32 by performing a catalyst imparting processing on the substrate W. Thereafter, a plating layer 35 is selectively formed on the plateable material portion 32 by supplying a plating liquid M1 onto the substrate W. The plating liquid M1 contains an inhibitor which suppresses the plating layer 35 from being precipitated on the non-plateable material portion 31.

An electronic circuit is made by selectively depositing an electrically conductive material seed layer conformally upon a three-dimensional substrate via the plurality of apertures of a three-dimensional mask. The substrate is then plated with more of the same electrically conductive material, or a different electrically conductive material, on the seed layer. In the case of electroplating, a nonconductive support structure is incorporated into a conductive clamp for making electrical connection to the seed layer. An environmentally protective layer may be deposited upon the electrically conductive material to such an extent that the electronic circuit remains solderable. The three-dimensional mask may be fabricated by an additive manufacturing technique.
