ABSTRACT:
The composite dielectric of the present invention contains an aromatic liquid crystal polyester and a dielectric ceramic powder arranged in the aromatic liquid crystal polyester, wherein the dielectric ceramic powder exhibits a Q value greater than 650 at a frequency of 1 GHz by perturbation. A wiring board comprising a composite dielectric sheet made of a composite dielectric having such a characteristic exhibits a high dielectric constant and a low dielectric dissipation factor, thereby yielding less transmission loss, and thus can favorably be used in electronic instruments driven in high-frequency regions.
