Patent ID: 7288950

Claim:
A contacting component having a probe contact formed by plating and adapted to be contacted with a target portion; the contacting component comprising an insulating substrate, a conductive circuit formed on one surface of the insulating substrate, and the probe contact made of a conductive material and formed on the other surface of the insulating substrate; the conductive circuit and the probe contact being electrically connected in a through hole penetrating the insulating substrate; the probe contact comprising a bump contact of a convex shape, the bump contact being formed by plating and having a surface which has a shape of a semispherical protrusion to be contacted with the target portion; the bump contact being made of a material containing a metal and carbon, the content of carbon falling within a range between 0.2 at % and 1.2 at % both inclusive; the bump contact being made of nickel or a nickel alloy as a main material, the carbon being contained in the form of nickel carbide.
