<p>[Problem] To provide an electronic component having as a dielectric layer a dielectric ceramic composition having high accelerated aging while satisfying an X8R capacitance temperature characteristic (a capacitance change rate of -15% to +15% at -55°C to 150°C). [Solution] A dielectric ceramic composition having a core/shell structure and being configured from BaTiO3 as a main component, Mg or the like as a first subcomponent, at least one element selected from Sc, Y, La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu as a second subcomponent, Mn or the like as a third subcomponent, Al or the like as a fourth subcomponent, and Zr or the like as a fifth subcomponent, the dielectric ceramic composition characterized by satisfying relational expressions such as CS2 > 10 (at%) and CS2/CP2 > 2.122, where CP2 is the concentration of the second subcomponent with respect to Ti in the dielectric ceramic composition, and CS2 (at%) is the concentration of the second subcomponent with respect to Ti in a shell part.</p> |
