ABSTRACT:
An anisotropic conductive sheet manufactured through improved manufacturing steps and a method of manufacturing the same. Conductive portions are unevenly arranged in a nonconductive elastomer having fluidity and serving as a matrix, the conductive portions highly densely containing the conductive particles having a specific gravity greater than that of the matrix component, the conductive particles are unevenly dispersed to form substantially nonconductive portions, and the conductive portions and the nonconductive portions are integrally cured to mold anisotropic conductive pieces. The anisotropic conductive pieces are so laminated that the conductive portions and the nonconductive portions are alternately arranged thereby to obtain a first laminate, and the first laminate is cut maintaining a predetermined thickness to obtain a zebra-like sheet. A second laminate obtained by alternately laminating the zebra-like sheets and the elastomer sheets is cut maintaining a predetermined thickness to obtain an isotropic conductive sheet in which the conductive portions are arranged like a matrix.
