Disclosed herein are a connector for measurement of electric resistance,
by which an electric resistance-measuring apparatus capable of surely performing
expected measurement of electric resistance with high precision even to a circuit
board having small-sized, protruding electrodes to be inspected, a scatter of projected
heights of said electrodes being great, and easy to produce can be constructed,
and electric resistance-measuring apparatus using this connector and method of measurement.
The connector has a composite electrode sheet having an insulating sheet body
in which through-holes have been formed corresponding to electrodes to be inspected,
movable electrodes supported movably in a thickness-wise direction within the through-holes,
and stationary electrodes each formed in the vicinity of openings of the through-holes
on a front surface of the insulating sheet body in a state coming into no contact
with the movable electrodes, front-side and back-side anisotropically conductive
elastomer layers respectively laminated on the front surface and back surface of
the composite electrode sheet, and an external leading terminal electrically connected
to the stationary electrodes. The movable and stationary electrodes are electrically
connected at the same time to corresponding electrodes to be inspected through
the front-side anisotropically conductive elastomer layer.
