PROBLEM TO BE SOLVED: To provide a resin composition which has excellent dielectric properties of a polyarylene ether copolymer, provides a cured product excellent in heat resistance and dimensional stability, and also has excellent moldability.SOLUTION: The resin composition contains: a polyarylene ether copolymer having an intrinsic viscosity of 0.03 to 0.12 dl/g as measured in methylene chloride at 25°C and having on average 1.5 to 3 of phenolic hydroxyl groups per molecule at molecular terminals; and thermosetting compounds including a benzoxazinone compound. The total content of the polyarylene ether copolymer and the benzoxazinone compound is 70 to 100 pts.mass, with respect to 100 pts.mass in total, of the polyarylene ether copolymer and the thermosetting compounds. |
