Dielectric ceramic composition comprising Bi₂O₃, ZnO, Nb₂O₅ and V₂O₅, dielectric ceramic, electronic device, and communication device

摘要

A dielectric ceramic composition is represented by a general formula “xBi₂O₃.yZnO.(z-a)Nb₂O₅.aV₂O₅”. The variables, “x”, “y”, “z” and “a” in the general formula respectively satisfy the following conditions: 2.90≦x≦3.10, 1.90≦y≦2.10, 1.90≦z≦2.10, and 0.0005≦a≦0.020.
