PROBLEM TO BE SOLVED: To provide dielectric ceramic having large dielectric constant, excellent in a temperature characteristic of the dielectric constant and in DC bias charac teristic, capable of increasing breakdown voltage of the dielectric ceramic even in the case for thin layer, and laminated electronic parts which is small in reduction rate of static capacitance under a high voltage, and excellent in reli ability, and a method of manufacturing the laminated electronic part. SOLUTION: The dielectric ceramic having BCT type crystal grain and BT type crystal grain, contains Mg and rare earth element. On the surface of BT type crystal grain, a covering layer composed of a composite oxide containing alkaline earth elements, rare earth elements and Si, is formed. |
