Abstract
Provided is a dielectric ceramic that includes a main component which contains MgSiOand additives which contain a zinc oxide and a glass component, in which, in X-ray diffraction. The peak intensity ratio, I/I, of the X-ray diffraction peak intensity Iof zinc oxide remaining unreacted, for which 2θ is between 31.0° and 32.0° and between 33.0° and 34.0°, with respect to the peak intensity Iof MgSiOas the main phase, for which 2θ is between 36.0° and 37.0°, is 10% or less. The dielectric ceramic has a relative density of 96% or greater.
