PURPOSE:To manufacture an anisotropic conductive film making connections among minute circuits in a constant connection thickness so as to provide high reliability in their respective connections also to lessen inequality in the connection resistance value of each of plural circuit terminals by having specified conductive particles contained in an insulating adhesive agent. CONSTITUTION:Conductive particles 3, 5 each having 3 to 7 volume % against the resin component of an insulating adhesive agent 6 are dispersed in the adhesive agent. The conductive particles 3, 5 having two different kinds of particle diameters and also having a particle-diameter range of + or -0.2 micrometer in the distribution of viscosity are prepared through the process of coating the surfaces of macromolecular core materials 1, 4 each having a difference of not less than 30% in hardness therebetween with metallic thin-layer 2 respectively. Hereupon the particles 3 each having a small diameter are specified to be harder than the particles 5 each having a large diameter. An anisotropic conductive film manufactured by using the conductive particles 3, 5 in this manner can make connections among many minute-circuits in a constant connection thickness while lessening inequality in the connection resistance value between their respective circuits to provide high reliability in their connections. |
