Abstract
An anisotropic electrically conductive film has a structure wherein the electrically conductive particles are disposed on or near the surface of an electrically insulating adhesive base layer, or a structure wherein an electrically insulating adhesive base layer and an electrically insulating adhesive cover layer are laminated together and the electrically conductive particles are disposed near the interface therebetween. Electrically conductive particle groups configured from two or more electrically conductive particles are disposed in a lattice point region of a planar lattice pattern. A preferred lattice point region is a circle centered on a lattice point. A radius of the circle is not less than two times and not more than seven times the average particle diameter of the electrically conductive particles.
