Filler-containing film

摘要: This filler-containing film 1A has a filler 2 and fine solid matter 3 that are retained in an insulating resin layer 10, the repeating predetermined array plan view. The repetition pitch rate after thermocompression bonding relative to before is within 300% if clamped with smooth surfaces thermocompression-bonded under conditions. One method for producing this includes: step forming 11 on release substrate 20a, pressing from surface side of opposite 20a; layering having pushed-in different 12 so substrates 20b thereof outer side. According 1A, disordered arraying suppressed case where onto article.
