[PROBLEMS] To improve the adhesive strength of an anisotropic conductive film using an acrylic monomer that initiates radical polymerization with an organic peroxide as a thermosetting adhesive main component without using phosphate group-containing acrylate or urethane acrylate. To be able to. An anisotropic conductive film is obtained by dispersing conductive particles in an insulating adhesive composition containing a (meth) acrylate monomer composition, a radical polymerization initiator, and a film-forming resin. The (meth) acrylate monomer composition contains a (meth) acrylate monomer having a cyclic ester residue or a cyclic amide residue. [Selection figure] None |
