Abstract
An anisotropic conductive film has a first insulating resin layer and a second insulating resin layer. The first insulating resin layer is formed of a photopolymerized resin, the second insulating resin layer is formed of a thermo-cationically or thermo-anionically polymerizable resin, a photo-cationically or photo-anionically polymerizable resin, a thermo-radically polymerizable resin, or a photo-radically polymerizable resin, and conductive particles for anisotropic conductive connection are disposed in a single layer on a surface of the first insulating resin layer on a side of the second insulating resin layer. The elastic modulus of the anisotropic conductive film as a whole is 0.13 MPa or more.
