Abstract: An anisotropic conductive film, capable of connecting a terminal formed on a substrate having a wavy surface such as a ceramic module substrate with conduction characteristics stably maintained, includes an insulating adhesive layer, and conductive particles regularly arranged in the insulating adhesive layer as viewed in a plan view. The conductive particle diameter is 10 μm or more, and the thickness of the film is 1 or more times and 3.5 or less times the conductive particle diameter. The variation range of the conductive particles in the film thickness direction is less than 10% of the conductive particle diameter.
