摘要： A dielectric ceramic composition for high frequency is obtained by using La and/or Nd in the main composition and iron as the additive. The main composition is expressed by the general formula x(CayTiO2+y)·(1−x)(LnzAl2−zO3) where Ln is at least one rare earth element containing La and/or Nd, and 0.600≦x≦0.730, 0.950≦y≦1.050, 0.980≦z≦1.030, and 0.01 to 0.5 parts by weight of iron as Fe2O3 is added to 100 parts by weight of the main composition. NiO may be comprised together with the Fe2O3.
