Abstract
An improved elastomer-based connector sheet for use to electrically connect electrode terminals is proposed which comprises, in the form of an integral sheet: (a) a matrix in the form of a sheet made from an electrically insulating rubber having a specified rubber hardness; and (b) a multiplicity of straightly extending wire segments of a metal having a specified volume resistivity and having a diameter in the range from 20 to 90 .mu.m embedded in the matrix of the rubber substantially in parallel each with the others in such a direction that the bias angle formed with the direction perpendicular to the surface of the sheet is in the range from 20.degree. to 60.degree. in such a fashion that each of the wire segments has the ends exposed on the surfaces of the matrix sheet and the distance between the surfaces of adjacent wire segments is at least 10 .mu.m, the distribution density of the ends of the wire segments exposed on the sur-face of the matrix sheet being in the range from 70 to 1000 per mm.sup.2.
