Provided is a connection terminal that maintains an approximately circular shape before or after a cylindrical part is fixed by resistance welding. The connection terminal used for a connection jig interconnecting target points includes a small-diameter conductive part and a large-diameter cylindrical part disposed to surround the small-diameter conductive part. The small-diameter conductive part has a front end protruding from a front end of the large-diameter cylindrical part. A part of the small-diameter conductive part is joined to a part of the large-diameter cylindrical part. A cutout part is formed in a part of a strip portion around an axis of the cylindrical part that at least includes the portion of the large-diameter cylindrical part which is joined to the small-diameter conductive part.

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.
