Claim 9:
10. A metal-clad laminate comprising:
an insulating layer including a resin composition and a fibrous base material; and
metal foil which is in contact with the insulating layer,
wherein:
the insulating layer has a dielectric dissipation factor (Df) of not more than 0.0100 at 10 GHz,
a surface of the metal foil has a ten-point average roughness (Rz) of not more than 2.0 μm, and
the metal-clad laminate has a 90-degree metal foil peel strength of not less than 0.43 N/mm and an interlaminar fracture toughness (G1c) of not less than 0.38 kJ/m2, the 90-degree metal foil peel strength being measured in accordance with JIS C6481, the interlaminar fracture toughness (G1c) being measured in accordance with ISO15024.
