Abstract
Provided is a micro contact element which is capable of coping with the miniaturization and greater complexity of substrates or boards, which is simplified due to a reduction in the number of components, and which creates sufficient contact pressure and stroke. Also provided is an inspection jig using this contact element. An inspection contact element having the contact pressure and amount of contraction required to carry out an inspection is formed by using notch parts respectively formed in two conductive cylindrical members having different outer and inner diameters so that the notch parts can function as elastic parts, and combining the two cylindrical members in such a way that the elastic parts are arranged in parallel or in series.
