Electrical contact member

摘要

Provided is an electrical contact member which is capable of maintaining stable conductivity over a long period of time, while achieving low adhesion to a test subject, in particular, an electrical contact member which is capable of maintaining stable electrical contact over a long period of time by suppressing increase in the contact resistance, while achieving low adhesion to a test subject even after repeated contact at high temperatures around 85° C. or after being left in the atmosphere for a long period of time. The present invention relates to an electrical contact member, which repeatedly comes into contact with a test subject, and wherein the surface of the electrical contact member, said surface coming into contact with the test subject, is configured of a carbon coating film that contains Pd.

主权项

1. An electrical contact member configured to contact a test subject repeatedly,
wherein a surface of the electrical contact member configured to come into contact with the test subject is a carbon coating film that comprises Pd, and wherein the electrical contact member has a topmost surface comprised of a Be—Cu alloy, a layer of an Au—Co alloy present on the topmost surface, a Layer of Ni on said layer of an Au—Co alloy, a layer of Cr on said layer of Ni, and said carbon coating film that comprises Pd present on said layer of Ni.
