Abstract
A micro-probe that has little deformation and wear while maintaining a desired conductivity is composed of a cylindrical wear resistant material and a conductive material. The wear resistant material provides mechanical contact with a contact target, while the conductive material provides an electrical contact with the contact target. The invention thus provides an ultra-small micro-probe having a long useful life, and that experiences little deformation or wear while maintaining the desired conductivity.
