Zusammenfassung:The present invention aims to provide: a dielectric ceramic composition which provides high breakdown AC voltage while maintaining various properties to be good; and an electronic component having a dielectric layer to which the same composition is applied. The dielectric ceramic composition includes a compound, represented by Formula of Ba_x(Ti_(1-y)Sn_y)O_3, and an oxide of Zn. In Formula, x is 0.970-0.996 and y is 0.050-0.130. The content of the Zn oxide is 1.5-8.0 parts by weight converted in terms of ZnO with respect to 100 parts by weight of a compound. The dielectric ceramic composition additionally includes an oxide of Nb. The content of the Nb oxide is 0.6 or less parts by weight converted in terms of Nb_2O_5 with respect to 100 parts by weight of the compound. (과제) 여러 가지 특성을 양호하게 유지하면서, 높은 교류 파괴 전압을 나타내는 유전체 자기 조성물을 제공하는 것 및 그 유전체 자기 조성물이 유전체층에 적용된 전자 부품을 제공하는 것. (해결 수단) 조성식 Ba(TiSn)O으로 나타내는 화합물과, Zn의 산화물을 함유하는 유전체 자기 조성물이다. 조성식 중의 x는 0.970∼0.996이고, y는 0.050∼0.130이다. Zn의 산화물 함유량이 화합물 100중량부에 대해서 ZnO 환산으로 1.5∼8.0중량부이다. 그 유전체 자기 조성물은 추가로 Nb의 산화물을 함유하고, Nb의 산화물 함유량이 화합물 100중량부에 대해서 NbO환산으로 0.6중량부 이하인 것이 바람직하다.
