PURPOSE: A manufacturing method of a lower contact terminal of a probe pin is provided to reduce the mass of metal material forming the lower contact terminal of a probe pin. CONSTITUTION: A metal sheet is cut and punched so that multiple arms form a radial shape. The mutually connected part of multiple arms is bent so that multiple arms are in parallel. The surfaces of multiple arms are cut in a C shape. A part which is cut in a C shape is bent to be mutually protruded in a radial shape. |
