Abstract
A metal-clad laminate and techniques using the metal-clad laminate are provided where the metal-clad laminate has excellent adhesiveness between a substrate and metal foil in addition to good dielectric characteristics and heat resistance. The metal-clad laminate includes an insulating layer in contact with metal foil where the insulating layer further includes a resin composition and a fibrous base material. The resin composition contains a specific resin (A) and specific core-shell polymer particles (B), and a surface of the metal foil has a ten-point average roughness (Rz) of not more than 2.0 μm.
