Patent ID: 7876088

Claim:
A method of producing a contacting component comprising an insulating substrate, a conductive circuit, and a probe contact, the method comprising: preparing the insulating substrate provided with a conductive metal film formed on one surface of the insulating substrate to serve as the conductive circuit; forming a through hole in the insulating substrate at a predetermined position; and forming the probe contact electrically connected to the conductive metal film by connecting one of plating electrodes to the conductive metal film and by carrying out electrolytic plating with the insulating substrate dipped into a plating solution, the probe contact formed by said electrolytic plating being made of a contact material comprising nickel or a nickel alloy as a main material and carbon; wherein the amount of an organic substance soluble in the plating solution and added to the plating solution is adjusted to control the content of the carbon in the probe contact formed by said electrolytic plating so that the content of the carbon falls within a range between 0.2 at % and 1.2 at % both inclusive.
