An anisotropic conductive film capable of responding to a narrow pitch bump and capable of reducing the number density of conductive particles compared to a conventional anisotropic conductive film is provided.
In the anisotropic conductive film 1A, the conductive particles 2 are disposed in the insulating resin binder 3, and when viewed in plan view, the polygonal repeating unit 5 formed by sequentially connecting the centers of the plurality of conductive particles 2 ) Are repeatedly arranged vertically and horizontally. The polygonal side of the repeating unit 5 is intersecting with the longitudinal direction or the width direction of the anisotropic conductive film.
