Abstract: A resin composition contains a preliminary reaction product obtained through mixing an epoxy resin and a monofunctional acid anhydride as a first curing agent in an equivalence ratio of the epoxy resin to the monofunctional acid anhydride in a range of 1:0.1 to 1:0.6, and reacting the epoxy resin and the monofunctional acid anhydride such that a percentage of ring opening of the monofunctional acid anhydride is 80% or more, and a second curing agent being a different compound from the monofunctional acid anhydride.

Abstract: A resin composition is used which contains a maleimide compound represented by the following Formula (1), a modified polyphenylene ether compound of which a terminal is modified with a substituent having a carbon-carbon unsaturated double bond, and a crosslinking agent containing an allyl compound. In Formula (1), s represents 1 to 5 and RA, RB, RC, and RD each independently represent a hydrogen atom, an alkyl group having 1 to 5 carbon atoms, or a phenyl group.
