简介 Provided is a dielectric ceramic comprising crystal particles with barium titanate as the main component and a boundary layer that is present between said crystal particles, and which comprises barium titanate as the main component and prescribed amounts of vanadium, magnesium, manganese and rare earth elements. In an X-ray diffraction chart, the diffraction intensity of the (004) face representing tetragonal crystal system barium titanate is greater than the diffraction intensity of the (004) face representing cubic crystal system barium titanate, and the mean particle diameter of the above crystal particles is 0.21-0.28 μm.
