Abstract:
Anisotropic conductive film produced that a light-transmitting transfer die having openings with conductive particles disposed therein is prepared, and photopolymerizable insulating resin squeezed into openings to transfer conductive particles onto the surface of the photopolymerizable insulating resin layer, first connection layer is formed which has a structure in which conductive particles are arranged in a single layer in a plane direction of photopolymerizable insulating resin layer and the thickness of photopolymerizable insulating resin layer in central regions between adjacent ones of the conductive particles is smaller than thickness of photopolymerizable insulating resin layer in regions in proximity to conductive particles; first connection layer is irradiated with ultraviolet rays through light-transmitting transfer die; release film is removed from first connection layer; second connection layer is formed on the surface of first connection layer opposite to light-transmitting transfer die; and third connection layer is formed on the surface of first connection layer.
