Abstract
An anisotropic conductive film contains conductive particles and spacers. The spacers are arranged at a central part of the film in a width direction. The central part of the film in the width direction represents 20 to 80% of the overall width of the film. The height of the spacers in the thickness direction of the anisotropic conductive film is larger than 5 μm and less than 75 μm. Such an anisotropic conductive film has a layered structure having a first insulating adhesion layer and a second insulating adhesion layer, wherein the conductive particles are dispersed in the first insulating adhesion layer, and the spacers are regularly arranged on a surface of the first insulating adhesion layer on a side of the second insulating adhesion layer.
