Abstract
An electrical connector includes an elastomer in the form of a layer, and a plurality of fine conductive wires embedded in the elastomer and extending rectilinearly in vertical directions to front and rear surfaces of the elastomer. The fine conductive wires have an overall length substantially the same as or slightly larger than the thickness of the elastomer so that both the ends of the fine conductive wires extend from the front and rear surfaces of the elastomer. The electrical connector includes a flexible printed circuit board connected to the fine conductive wires. The flexible printed circuit board includes at least three electric contacts arranged substantially concentrically around and electrically connected to each of the fine conductive wires. With this arrangement, the electrical connector enables a stable inspection for integrated circuit pads in a manner which minimizes irregularities in repeatedly measured values of electric resistance and skew.
