Title: ELASTIC CONDUCTOR SHEET AND PASTE FOR FORMING ELASTIC CONDUCTOR SHEET
Abstract:
A first purpose of the present invention is to provide an elastic conductor sheet exhibiting isotropic electrical conductivity when stretched in a predetermined direction or a direction perpendicular thereto, and to provide a paste used for the same for forming the elastic conductor sheet. A second purpose of the present invention is to provide an elastic conductor sheet whereby a change in specific resistance thereof is small even when the sheet is repeatedly subjected to twisting, and to provide a paste used for the same for forming the elastic conductor sheet. A third purpose of the present invention is to provide an elastic conductor sheet whereby a change in specific resistance thereof is small even when the sheet is repeatedly subjected to washing, and to provide a paste used for the same for forming the elastic conductor sheet. The first purpose can be achieved by an elastic conductor sheet having a thickness of 3-800 µm and containing at least electroconductive particles, inorganic particles surface-treated by a hydroxide and/or oxide of one or both of Al and Si, and a flexible resin having a modulus of elongation of 1 MPa to 1000 MPa, wherein the variation in specific resistance of the elastic conductor sheet during stretching in an elongation direction when stretched 40% of the original length thereof in any of two orthogonal directions is less than ±10%.
