Abstract
The present invention provides an anisotropic electrically conductive film with a structure, in which electrically conductive particles are disposed at lattice points of a planar lattice pattern in an electrically insulating adhesive base layer. A proportion of the lattice points, at which no electrically conductive particle is disposed, with respect to all the lattice points of the planar lattice pattern assumed as a reference region, is less than 20%. A proportion of the lattice points, at which plural electrically conductive particles are disposed in an aggregated state, with respect to all the lattice points of the planar lattice pattern, is not greater than 15%. A sum of omission of the electrically conductive particle and an aggregation of the electrically conductive particles is less than 25%.
