ABSTRACT:
A connector for measurement of electric resistance, an electric resistance-measuring apparatus for circuit boards, and methods of measurement of electric resistance. The connector includes an insulating base plate, a plurality of connecting electrode pairs provided on a front surface of the insulating base plate, and composed of core electrodes arranged in accordance with a pattern corresponding to a pattern of a plurality of electrodes to be inspected in a circuit board to be inspected and ring-like electrodes arranged to surround the respective core electrodes in a state electrically insulated from the core electrodes, and a plurality of relay electrodes provided on a back surface of the insulating base plate and electrically connected to either one of the core electrode or ring-like electrode of the connecting electrode pairs.
