Claim 0:
1. A polyphenylene ether resin composition comprising:
a modified polyphenylene ether compound (A) that is terminally modified with a substituent having a carbon-carbon unsaturated double bond, and
a crosslinking-type curing agent (B) distinct from the modified polyphenylene ether compound (A) and having two or more carbon-carbon unsaturated double bonds in each molecule and capable of curing the modified polyphenylene ether compound (A),
the modified polyphenylene ether compound (A) including
a modified polyphenylene ether compound (A-1) represented by formula (1), and
a modified polyphenylene ether compound (A-2) represented by formula (2):, wherein in formulas (1) and (2), R1 to R8 and R9 to R16 each independently represent a hydrogen atom, an alkyl group, an alkenyl group, an alkynyl group, a formyl group, an alkylcarbonyl group, an alkenylcarbonyl group, or an alkynylcarbonyl group; Y represents a linear, branched or cyclic hydrocarbon having 20 or less carbon atoms; X1 and X2, which may be the same or different from each other, represent a substituent having a carbon-carbon unsaturated double bond; and A and B respectively represent structures shown by formulas (3) and (4):, wherein in formulas (3) and (4), m and n each represent an integer of 0 to 20; and R17 to R20 and R21 to R24 each independently represent a hydrogen atom or an alkyl group;
wherein in formula (1) and formula (2), X1 and X2 are substituents represented by formula (6) or formula (7):, wherein in formula (6), a represents an integer of 0 to 10, and Z represents an arylene group; and R27 to R29 each independently represent a hydrogen atom or an alkyl group;, wherein in formula (7), R30 represent a hydrogen atom or an alkyl group; and
wherein in the modified polyphenylene ether compound (A), the content ratio between the modified polyphenylene ether compound (A-1) and the modified polyphenylene ether compound (A-2) is (A-1):(A-2)=3.5:66.5 to 21:49 by mass ratio.
