There is provided with a metal foil-releasable resin layer composite comprising a metal foil and a releasable resin layer on at least one surface of the metal foil, wherein the releasable resin layer includes 100 parts by mass, in total, of (A) 50 to 95 parts by mass of a nonpolar resin, (B) 4 to 40 parts by mass of a thermosetting resin, and (C) 1 to 25 parts by mass of a release agent, wherein the mass ratio (A/B) of the nonpolar resin (A) to the thermosetting resin (B) is 55/45 to 96/4. The metal foil-releasable resin layer composite can achieve release with significantly low release strength between the metal foil and the releasable resin layer without damage of the releasable resin layer and can withstand hot pressing. |
