A nonreducing dielectric ceramic contains a tungsten-bronze-type crystal phase including at least Ba, RE and Ti as elements, and a pyrochlore-type crystal phase including at least RE and Ti as elements, where RE is at least one rare-earth element. The relationship 0.10<=b/(a+b)<=0.90 is satisfied, where a is the maximum peak intensity assigned to the tungsten-bronze-type crystal phase and b is the maximum peak intensity assigned to the pyrochlore-type crystal phase determined by X-ray diffractometry. A ceramic electronic component includes an electronic component body composed of the nonreducing dielectric ceramic and a conductor in contact with the nonreducing dielectric ceramic.
