An anisotropic conductive film comprises an insulating adhesive agent composition comprising a (meth)acrylate monomer composition, a radical polymerization initiator and a film-forming resin and electrically conductive particles dispersed in the insulating adhesive agent composition. The (meth)acrylate monomer composition contains a (meth)acrylate monomer having a cyclic ester residue or a cyclic amide residue represented by formula (1). In the formula, R1 represents a hydrogen atom or a methyl group; R2 represents an alkylene group or an alkyloxy group; R3 represents an alkyl group, an alkylene group, an aryl group or a halogen atom; n represents an integer of 0-3; R4 is absent or represents an alkylene group which may be substituted by an oxygen atom, wherein broken lines on both sides of R4 independently represent a single bond when R4 is absent; X1 is absent or represents an oxygen atom or a carbon atom, wherein solid lines on both sides of X1 independently represent a single bond when X1 is absent; and X2 represents an oxygen atom, a nitrogen atom or a sulfur atom. |
