PURPOSE: An aniotropically conductive film composition is provided to obtain adhesion while enduring stress generated from both ends of a connection substrate under compression due to heat and pressure. CONSTITUTION: An aniotropically conductive film composition has an elastic modulus of 4,000-10,000 MPa at 50°C after curing, and a glass transition temperature(Tg) of 110-150°C after curing. The aniotropically conductive film composition comprises an acrylate-modified urethane resin, a diene-based rubber, an elastically reinforced resin, a radically polymerizable material, a polymerization initiator, and conductive particles. The elastically reinforced resin is one or more selected from a cellulose based resin and a styrene based resin. The elastically reinforced resin comprises 20-50 weight% of the cellulose based resin and 50-80 weight% of the styrene based resin.
