Abstract: In the dielectric ceramic of this invention, a perovskite-type crystal phase is precipitated as a main crystal phase and a complex oxide crystal phase other than the perovskite-type crystal phase is precipitated as a sub-crystal phase, wherein the above perovskite-type crystal phase contains Mg, W, an iron family metal elements and/or Zn and Ba and/or Sr as metal elements, and the complex oxide crystal phase contains W, and Ba and/or Sr as metal elements and the main crystal phase and the sub-crystal phase have a peak intensity ratio by X-ray diffraction of formula (1):I.sub.112 /I.sub.211 <0.10 (1)wherein I.sub.112 represents a peak intensity of the (112) plane in a tetra-gonal system in the above sub-crystal phase, and I.sub.211 represents a peak intensity of the (211) plane in a rhombohedral system in the main crystal phase.
