(57) Abstract: An anisotropic conductive film in which conductive particles are dispersed in an adhesive and imparted with conductivity in the thickness direction by applying pressure in the thickness direction. An anisotropic conductive film, wherein the agent is a thermosetting or photocurable adhesive containing a polymer obtained by acetalizing polyvinyl alcohol as a main component. The anisotropic conductive film of the present invention has a high adhesive strength, a good workability, a high resistance to humidity and heat, and a conductivity in the thickness direction even after being kept for a long time at high humidity and high temperature. It maintains the insulation in the direction, has high adhesive strength, and has excellent durability. |
