A contacting component has a probe contact formed by plating and adapted
to be contacted with a target portion. The contacting component includes
an insulating substrate, a conductive circuit formed on one surface of
the insulating substrate, and the probe contact is made of a conductive
material and formed on the other surface of the insulating substrate. The
conductive circuit and the probe contact are electrically connected in a
through hole penetrating the insulating substrate. The probe contact
includes a bump contact of a convex shape, the bump contact is 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 is
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.
