The apparatus which could be measured both contact and rubber resistance was made. Contact resistance between bare metals and rubber was studied. The metal were brass, gold, silver and plati-
num. Contact resistivity, as the way to characterize contact, was also evaluated its possibility.
Contact resistance was independent from type of metals. Contact resistivity could be used to characterize a contact, but current density should be specified.
Contact resistance measured from this apparatus was reasonable, but an error in rubber resis-
tance was appeared. This could be caused by high contact resistance of the needles which were used
as voltage probes and position of needles.
