Abstract:
1. An anisotropic electrically conductive film formed of a thermosetting acrylic resin composition, the film comprising: a thermosetting agent (A) being a peroxide-based initiator; a thermo-settable ingredient (B) including a phosphous-containing acrylic ester (b1); an acrylic rubber containing hydroxyl groups (C), wherein the weight averaged molecular weight of the acrylic rubber containing the hydroxyl groups (C) being not less than 1000000; organic fine particles (D) being polybutadiene-based fine particles (d1 ), wherein the amount of the polybutadiene-based fine particles (d2 ) being not less than 2 times the weight of the acrylic rubber containing the hydroxyl groups (C); and electrically conductive particles (E), wherein the adhesive force in the anisotropic conductive film is not less than 6N/cm.
