CONTACTING COMPONENT, METHOD OF PRODUCING THE SAME, AND TEST TOOL HAVING CONTACTING COMPONENT

摘要

PURPOSE: A contacting component and a method of producing the same are provided to obtain a probe contact having good hardness and resistance of broken by controlling the size of particle and the content of carbon in the probe contact. CONSTITUTION: An insulating substrate(1) with a conductive metal film(4) is prepared. A through-hole(5) is formed. A probe contact(2) is formed by plating and adapted to be contacted with a target portion. The probe contact is made of a polycrystalline material having a crystal grain size not smaller than 10 nm and not greater than 40 nm.
