PURPOSE: An anisotropic conductive film is provided to maintain excellent indentation characteristic when the pressure after compression is removed, and to realize high adhesive property and electricity reliability. CONSTITUTION: An anisotropic conductive film includes a thermoplastic resin, an epoxy-based thermosetting resin, a hardener, conductive particles and a release film. An elastic recovery index(ε) represented by the formula:ε=(L2/L1) has a value satisfying 0.05<=ε<=0.15. In chemical formula, L1 is the length extended when the anisotropic conductor film is drawn by 2 kgf/cm^2 tensile force before hardening; and L2 is the length shortened when 2 kgf/cm^2 tensile force is removed. |
