In order to obtain a 3D circuit board manufacturing method capable of improving productivity and accuracy of circuit formation, the metal hoop material 1 provided with the positioning pilot holes 2 is employed. Since the 3D structures 3 are formed on the hoop material 1 with a preset interval maintained therebetween in a lengthwise direction of the hoop material 1, the series of processes can be conducted on a roll 1A (winding of the hoop material 1) basis, which results that handling between the individual processes can be done more easily while increase of troubles and manufacturing costs can be prevented. Further, since the positioning pilot holes 2 serve to facilitate accurate positioning, plating and/or laser processing can be conducted continuously with high precision while a tact time for the positioning work can be reduced.

In a contact for a connector, a metal material id processed to be bent in a predetermined shape in a manner so that a terminal portion is formed in the vicinity of an end and a contacting portion is formed in the vicinity of the other end. A nickel plating layer as a foundation plating layer and a gold plating layer are formed on substantially entire surface of the contact including the terminal portion and the contacting portion. Laser beams are irradiated at a portion between the terminal portion and the contacting portion, and especially in the vicinity of the terminal portion so that the nickel plating layer as the foundation plating layer is unsheathed by removing the gold plating layer or gold in the gold plating layer and nickel in the foundation layer are alloyed. Nickel and the alloy of nickel and gold respectively have low wetting property with respect to solder, so that diffusion of melted solder stops at the portion.

A three-dimensional object is fabricated from a light curable liquid resin by repeating the following process to superimpose a plurality of cured resin layers. The process utilizes a vessel containing a volume of the liquid resin and a vertically movable platform. In the process, the platform is immersed in the liquid resin in the vessel to dispose an overlay surface of an immediately previously cured layer sufficiently below the liquid level of the liquid resin. The platform is then raised such that the overlay surface is slightly higher than the liquid level of the liquid resin in the vessel, while keeping the liquid resin on the overlay surface connected with the surrounding liquid resin in the vessel by the effect of surface tension acting on the liquid resin. An excess amount of the liquid resin on the overlay surface is removed to form a liquid resin layer having a desired thickness. The platform is lowered such that an upper surface of the liquid resin layer is substantially in flush with the surrounding liquid level in the vessel, while keeping the desired thickness of the liquid resin layer. A light is then radiated to the liquid resin layer so as to cure it into the cured resin layer.
