Abstract
An anisotropic conductive film comprising an insulating film and plural conductive paths ( ), wherein the plural conductive paths are insulated from each other and penetrate the insulating film in the thickness direction of the film, with both ends of the paths being exposed on both surfaces of the insulating film, and wherein a conductive path capable of contact with an electrode of a semiconductor element and a circuit of a circuit board has at least one end protruding more than an end on the same side of a conductive path incapable of contact with the electrode and the circuit. The ACF of the present invention can prevent a conductive path not involved in electrical connection from being in contact with a part other than an electrode of a semiconductor element and/or a part other than a circuit of a circuit board.
