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.

Sintered body, method for producing same, and dielectric composition

To provide a dielectric porcelain composition and an electronic component that demonstrate ferroelectricity. A dielectric porcelain composition that is characterized by having a perovskite-type oxynitride as a principal component and by including a polycrystalline body that demonstrates ferroelectricity.
