Abstract
An anisotropic conductive film capable of accommodating bumps with a narrow pitch and reducing the number density of conductive particles. In an anisotropic conductive film, conductive particles are disposed in an insulating resin binder as follows. Specifically, the conductive particles are rows of conductive particles arranged in single rows with spacing therebetween; and repeating units of conductive particles formed by juxtaposition of different numbers of conductive particles are disposed repeatedly over the entire surface of the anisotropic conductive film.
