Abstract:
Disclosed are a connector for measurement of electric resistance, by which necessary electrical connection is surely achieved even when a circuit board to be inspected is large in area and has a great number of small-sized electrodes to be inspected, and measurement is surely performed with high precision, and which can be produced at a low cost, and an electric resistance-measuring apparatus and an electric resistance-measuring method for circuit boards, which make use of this connector. The connector for measurement of electric resistance has a first electrode sheet, an anisotropically conductive elastomer sheet arranged on a back surface of the first electrode sheet and having through-holes formed corresponding to the electrodes to be inspected, and a second electrode sheet arranged on a back surface of the anisotropically conductive elastomer sheet. The first electrode sheet has an insulating sheet having through-holes formed corresponding to the electrodes to be inspected, a plurality of ring-like electrodes each formed on a front surface of the insulating sheet so as to surround the through-hole, and junction electrodes formed on a back surface of the insulating sheet, and the second electrode sheet has a plurality of core electrodes for inspection arranged corresponding to the electrodes to be inspected, and a plurality of core electrodes for connection arranged corresponding to the junction electrodes.
