ANISOTROPIC CONDUCTIVE FILM AND METHOD OF PRODUCING THE SAME

摘要

An anisotropic conductive film has a three-layer structure in which a first connection layer is sandwiched between a second connection layer and a third connection layer that each are formed mainly of an insulating resin. The first connection layer has a structure in which conductive particles are arranged in a single layer in the plane direction of an insulating resin layer on a side of the second connection layer, and the thickness of the insulating resin layer in central regions between adjacent ones of the conductive particles is smaller than that of the insulating resin layer in regions in proximity to the conductive particles.
