Abstract
The anisotropic conductive film of the present invention includes a resin base tape and a plurality of composite fibers disposed laterally in the resin base tape, wherein each of the composite fibers includes an electrically insulating fiber and a plurality of conductive rings circling the electrically insulating fiber, the conductive rings including a plurality of conductive particles collectively surrounding the electrically insulating fiber by adsorption, wherein the plurality of composite fibers are periodically arranged in the resin base tape along the extending direction of the resin base tape, and the plurality of conductive rings on each of the composite fibers are periodically arranged along the axial direction of the electrically insulating fiber thereof.
