摘要： A sintered body containing polycrystalline grains of a metal oxynitride containing at least two metal elements, wherein Ba and at least one metal element of a crystal phase of the sintered body are contained in a triple point that is not a void between the polycrystalline grains. A method for producing the sintered body includes sintering a mixture of at least a metal oxynitride as a main component and a sintering aid containing cyanamide in an atmosphere containing nitrogen or a rare gas or in a reduced-pressure atmosphere of 10 Pa or less while applying a mechanical pressure with a retention time at a maximum heating temperature during the sintering set to 1 minute to 10 minutes.

摘要： A dielectric composition comprises a crystal of an oxynitride. A peak attributed to absence of a center of symmetry of the crystal of the oxynitride is detected by Raman spectroscopy of the dielectric composition within a Raman shift range of 500 cm−1 or less.
