摘要: A multilayer ceramic electronic component comprises an element body obtained by stacking dielectric layers (thickness t1) and electrode layers (thickness t2). The dielectric layer includes a compound expressed by ABO3 (A includes Ba, and may include Ca or Sr; and B includes Ti, and may include Zr or Hf), and includes 0.75 to 2.0 moles of MgO, 0.4 to 1.0 mole of an oxide of Y, Dy, Ho and the like in terms of the oxide, and 0.4 to 0.8 mole of SiO2 per 100 moles of the compound. A segregation phase containing Mg is formed in at least a part of an electrode missing portion. Line coverage of the electrode layer is 60 to 90% and relations of 0.3 μm≦t1≦2.0 and 0.3 μm≦t2

摘要: A dielectric ceramic composition comprising a main component and at least one or more subcomponent elements has a dielectric particle and a grain boundary. The dielectric particle has a main component phase substantially composed of the main component, and a diffusive phase around the main component phase where at least one selected from the subcomponent elements is diffused, a local minimal value of Cs is located at an outside edge side with respect to a position of the local maximum value of Cs, and Cs is increased from a position of the local minimal value of Cs toward the outside edge, when the dielectric particle is cut on an arbitrary cutting plane including the main component phase, and Cs is defined as a concentration of one or more elements selected from the subcomponent elements in an arbitrary position in the dielectric particle.
