Abstract:
1. A connector for measurement of electric resistance, comprising a first electrode sheet, an anisotropically conductive elastomer sheet arranged on a back surface of the first electrode sheet and a second electrode sheet arranged on a back surface of the anisotropically conductive elastomer sheet, wherein the first electrode sheet has a flexible insulating sheet having a plurality of through-holes formed in accordance with a pattern corresponding to a pattern of electrodes to be inspected in a circuit board, the electric resistance of which is to be measured, a plurality of ring-like electrodes each formed on a front surface of the insulating sheet so as to surround the through-hole in the insulating sheet, and junction electrodes each formed on a back surface of the insulating sheet and electrically connected to the ring-like electrode, wherein the anisotropically conductive elastomer sheet has a plurality of through-holes formed in accordance with the pattern corresponding to the pattern of the electrodes to be inspected, wherein the second electrode sheet has a first plurality of core electrodes for inspection arranged in accordance with the pattern corresponding to the pattern of the electrodes to be inspected, a second plurality of core electrodes for connection arranged in accordance with a pattern corresponding to a pattern of the junction electrodes in the first electrode sheet, and an insulating support sheet supporting the core electrodes for inspection and the core electrodes for connection, and wherein the core electrodes for inspection each enter the through-hole in the anisotropically conductive elastomer sheet and the through-hole in the insulating sheet of the first electrode sheet to be electrically connected to an electrode to be inspected.
