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 2):
The resin-clad copper foil according to  claim 1 ,\n wherein the bismaleimide resin represented by the above general formula (I) is a compound in which X in general formula (I) has an alkyl group having 10 to 30 carbon atoms as the main chain, and two side chains bonded to mutually adjacent carbons in the alkyl group partially form a cyclic structure.
