<p>Provided are an anisotropic conductive film, which has a good insulation property in narrow space and improves connection reliability at a fine connection pitch, and a circuit board using the same. The anisotropic conductive film is interposed between circuit electrodes facing each other, applies pressure to the facing circuit electrodes, and connects pressure-directional electrodes to each other electrically. The anisotropic conductive film is a laminate consisting of a first adhesive film layer and a second adhesive film layer. The first adhesive film layer contains a polymer of photo-polymerizable resin composed of any one selected from acrylate, methacrylate, or maleimide, an epoxy resin, a hardener for epoxy resins, and conductive particles. The second adhesive film layer contains an epoxy resin and a hardener for epoxy resins.</p> |
