Abstract

See full text

An anisotropic conductive film has a first connection layer and a second connection layer formed on surface of the first connection layer. The first connection layer is a photopolymerized resin layer, and the second connection layer is a thermo- or photo-cationically, anionically, or radically polymerizable resin layer. On the surface of first connection layer on the side of second connection layer, conductive particles for anisotropic conductive connection are arranged in a single layer. A region in which the curing ratio is lower than that of the surface of the first connection layer exists in a direction oblique to the thickness direction of the first connection layer. Alternatively, the curing ratio of a region relatively near another surface of the first connection layer among regions of the first connection layer in the vicinity of the conductive particles is lower than that of the surface of the first connection layer.
