Abstract: A resin composition which comprises: a modified polyphenylene ether having, at a terminal, a group represented by a formula (1) given below; a radical-polymerizable compound having, only at molecular terminals, two or more bonds or groups of at least one selected from the group consisting of a carbon-carbon unsaturated double bond and a maleimide group; a styrene-based thermoplastic elastomer in which repeating units having a carbon-carbon unsaturated double bond not belonging to an aromatic ring are contained in an amount less than 10 mol % with respect to all the repeating units; and an organic peroxide. In the formula (1), R1 represents a hydrogen atom or an alkyl group.

Abstract: A metal-clad laminate includes: an insulating layer; and a metal foil being in contact with at least one surface of the insulating layer. The insulating layer contains a cured product of a resin composition containing a polyphenylene ether copolymer having an intrinsic viscosity of 0.03 to 0.12 dl/g measured in methylene chloride at 25° C. and having an average of 1.5 to 3 specific groups per molecule at its molecular terminal, a thermosetting curing agent having two or more carbon-carbon unsaturated double bonds at its molecular terminal, and a thermoplastic elastomer. The metal foil includes a metal substrate, and a cobalt-containing barrier layer provided on at least a contact surface of the metal substrate, the contact surface being in contact with the insulating layer. The contact surface has a ten-point average roughness Rz of 2 μm or less as a surface roughness.
