Abstract: A filler-containing film has a structure in which fillers are held in a binder resin layer. The average particle diameter of the fillers is 1 to 50 μm, the total thickness of the resin layer is 0.5 times or more and 2 times or less the average particle diameter of the fillers, and the ratio Lq/Lp of, relative to the minimum inter-filler distance Lp at one end of the filler-containing film in a long-side direction, a minimum inter-filler distance Lq at the other end at least 5 m away from the one end in the film long-side direction is 1.2 or less. The fillers are preferably arranged in a lattice form.

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.
