Abstract:
1. A contactor which is placed between a semiconductor device and a test board so as to electrically connect said semiconductor device to said test board, said contactor comprising: an insulating substrate; and a plurality of contact electrodes formed by etching a conductive layer plated onto said insulating substrate, each of the contact electrodes comprising a first elongated contact piece which contacts a terminal of said semiconductor device, a second elongated contact piece which contacts an electrode of said test board, and a connecting portion which electrically connects said first contact piece and said second contact piece, wherein the conductive layer is plated onto the substrate and each contact electrode is formed by etching portions of the conductive layer off of the substrate, wherein both the first contact piece and the second contact piece are movable contact pieces and are elastically movable by a pressing force applied thereto, and wherein the first and second contact pieces are aligned through a center of the contact electrode defining a longitudinal direction, wherein each of said first contact piece and said second contact piece is placed so that the longitudinal direction thereof is on a line extending in a radial direction from a center of said insulating substrate.
