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.

Abstract: An anisotropic conductive film that can be produced in high productivity and can reduce a short circuit occurrence ratio has a first conductive particle layer in which conductive particles are dispersed at a predetermined depth in a film thickness direction, and a second conductive particle layer in which conductive particles are dispersed at a depth different from that in the first conductive particle layer. In the respective conductive particle layers, the closest distances between the adjacent conductive particles are 2 times or more the average particle diameters of the conductive particles.
