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.
