摘要:
A dielectric ceramic is provided having a high relative dielectric constant, and in the case in which it is used for a multilayer ceramic capacitor (1), even when the thickness of a dielectric ceramic layer (3) is decreased, high insulating properties and superior reliability can be obtained. The dielectric ceramic has a composition represented by 100(Ba 1-w-x-m Ca w Sr x Gd m ) k (Ti 1-y-z-n Zr y Hf z Mg n ) 0 3+a + pMnO 2 + qSiO 2 + rCuO, and is used for forming the dielectric ceramic layer (3) of a multilayer ceramic capacitor 1. However, 0.995≤k≤1.010, 0≤w
