ANISOTROPIC CONDUCTIVE FILM AND PRODUCTION METHOD OF THE SAME

摘要

A first anisotropic conductive film 1A or a second anisotropic conductive film 1B has a first insulating resin layer 2 and a second insulating resin layer 3. The first insulating resin layer 2 is formed of a photopolymerized resin, and the second insulating resin layer 3 is formed of a polymerizable resin. Conductive particles 10 are disposed in a single layer on a surface of the first insulating resin layer 2 on a side of the second insulating resin layer 3. The first anisotropic conductive film further has a third insulating resin layer 4 formed of a polymerizable resin, and the second anisotropic conductive film 1B has an intermediate insulating resin layer 6. The intermediate insulating resin layer 6 is formed of a resin containing no polymerization initiator, and is in contact with the conductive particles 10. These anisotropic conductive films have favorable connection reliability.
