1. A metal-clad laminate comprising:
an insulating layer including a resin composition and a fibrous base material; and
metal foil in contact with the insulating layer,
wherein the resin composition contains:
a resin (A) having a dielectric dissipation factor (Df) of not more than 0.0100 at 10 GHz, and core-shell polymer particles (B) having a volume-average particle size of 10 nm to 400 nm;
the core-shell polymer particles (B) include a shell layer that contains an epoxy group; and
a surface of the metal foil has a ten-point average roughness (Rz) of not more than 2.0 μm.
