CONDUCTIVE CERAMIC COMPOSITION, CONDUCTIVE MEMBER, AND CERAMIC ELECTRONIC COMPONENT
PROBLEM TO BE SOLVED: To provide a conductive ceramic composition having such good conductivity as to have low resistivity having no inferiority in comparison with a metal material and to keep low resistivity even when heat-treated in atmosphere; a conductive member using the conductive ceramic composition; and a ceramic electronic component such as a laminated ceramic capacitor using the conductive member as an electrode.SOLUTION: A conductive ceramic composition contains a main component having a perovskite crystal structure represented by general formula {Sr(VTiZr)O}. In general formula, m is 0.90≤m≤1.10; and x and y satisfy any one of (i) 0.1≤x≤0.6 and y=0, (ii) x=0 and 0.05≤y≤0.15, and (iii) 0.1≤x≤0.6, 0.05≤y≤0.15 and x+y≤0.3. At least internal electrodes 2a to 2f are formed of a conductive member containing the conductive ceramic composition as a main component.SELECTED DRAWING: Figure 1
