    摘要: PROBLEM TO BE SOLVED: To manufacture an anisotropic conductive film exhibiting good connection reliability, good insulation properties and good particle capture efficiency, in manufacturing an anisotropic conductive film in which conductive particles are arranged in a single layer by using a transfer mold with an opening.SOLUTION: An anisotropic conductive film is manufactured as follows: a photopolymerizable insulating resin is pressed into an opening of a light-transmitting transfer mold having the opening, in which conductive particles are disposed, so as to transfer the conductive particles to the surface of a photopolymerizable insulating resin layer, thereby forming a first connection layer having a structure where the conductive particles are arranged in a single layer in the direction of the plane of the photopolymerizable insulating resin layer and the thickness of the insulating resin layer in the central region between adjacent conductive particles is thinner than that of the insulating resin layer near the conductive particles; the first connection layer is irradiated with ultraviolet rays from the light-transmitting-transfer-mold side; a release film is removed from the first connection layer; a second connection layer is formed on the surface of the first connection layer on the opposite side thereof from the light-transmitting transfer mold; and a third connection layer is formed on the surface of the first connection layer on the opposite side thereof from the second connection layer.
