A curable polyphenylene ether-based resin composition having excellent adhesive strength to a conductor, a high-density wiring board material and a wiring board using the same, which are suitable for high-frequency applications, are provided. A low dielectric constant / low dielectric constant excellent in adhesion to a conductor is obtained by using a composition containing polyphenylene ether, a crosslinkable compound, and a hydrogenated product of a specific functional group-modified block copolymer. A lossy wiring board can be obtained. [Selection diagram] No selection diagram. |
