In the anisotropic conductive film, a photopolymerizable insulating resin is press-fitted into the opening of a light-transmitting transfer type in which conductive particles are arranged in the opening, and conductive particles are electrodeposited on the surface of the photopolymerizable insulating resin layer, whereby photopolymerizable insulating property A structure in which conductive particles are arranged in a single layer in the plane direction of the resin layer, and the thickness of the photopolymerizable insulating resin layer in the central region between adjacent conductive particles is thinner than the thickness of the photopolymerizable insulating resin layer in the vicinity of the conductive particles Forming a first connection layer of, irradiating ultraviolet rays to the first connection layer from the light-transmitting transfer type side, removing the release film from the first connection layer, and removing the surface of the first connection layer opposite to the light-transmitting transfer type It is produced by forming a second connection layer on the second connection layer and forming a third connection layer on the surface of the first connection layer on the opposite side from the second connection layer. |
