Abstract
In a filler-containing film in which fillers are dispersed in a resin layer, a flow of the fillers caused by an unnecessary flow of the resin layer is suppressed during the pressure bonding of the filler-containing film and an article. This filler-containing film (A) includes a filler-dispersed layer () in which fillers () are dispersed in a resin layer (). The surface in the vicinity of the fillers () of the resin layer () has concavities () and () with respect to the tangent plane to the central portion of the surface of the resin layer () between adjacent fillers (). The ratio (La/D) of a layer thickness La of the resin layer () to a particle diameter D of the filler () is preferably from 0.6 to 10.
