Abstract

When a sheet is molded with an anisotropic conductor sheet molding mold having a plurality of magnetic micropoles, ferromagnetic particles are localized in a state in which the magnetic field intensity distribution in a sheet molding space shows the maximum substantially on the central axis of each pair of opposing magnetic micropoles, whereby an anisotropic conductor sheet containing ferromagnetic particle aggregate portions free of any low-density parts in the particle distribution, when viewed from above a sheet surface, can be obtained. This anisotropic conductor sheet is low in conduction resistance and capable of attaining a good electric connection by a little compression dislocation thereof.
