Abstract:
Resin-clad copper foil improves transmission characteristics by using a bismaleimide resin having a low dielectric constant and a low dielectric loss tangent. The foil can be manufactured without irradiation with ultraviolet rays. A resin composition is laminated on copper foil. The resin composition includes a bismaleimide resin represented by general formula (I), a curing agent, and a filler, the blending amount of the filler is 10 to 200 parts by mass based on 100 parts by mass of a resin component. The resin composition has a complex viscosity at 80° C. of 1×10 3  Pa·s to 5×10 5  Pa·s. In general formula (I), X represents an aliphatic, alicyclic or aromatic hydrocarbon group having 10 to 30 carbon atoms in the main chain, Y represents an aliphatic, alicyclic, or aromatic hydrocarbon group, and a represents a number in a range of 1 to 20.

Claim (Index 3):
The resin-clad copper foil according to  claim 1 ,\n wherein the filler is silica and/or fluororesin powder.
