Provided is a dielectric ceramic composition that enables a laminated ceramic capacitor having good capacitance-temperature characteristics, from low to high temperatures, to be obtained without a decrease in the insulation resistance of dielectric ceramic layers even when fired in a reduction atmosphere. The laminated ceramic capacitor (10) includes a ceramic body (12) obtained by laminating dielectric ceramic layers (14) and internal electrodes (16) composed mainly of nickel, and external electrodes (18) formed on the outer surface of the ceramic body (12). The dielectric layers (14) are formed using a dielectric ceramic composition that: is represented by (KaNabLicM2d)(NbwTaxMgyM4z)O3, wherein M2 is at least one of calcium, strontium and barium, and M4 is at least one of zirconium, hafnium and tin; contains main ingredients in which a, b, c, d, w, x, y and z satisfy prescribed relationships; and contains 2 to 15 molar parts of manganese with respect to 100 molar parts of the total content of niobium, tantalum, magnesium and M4. |
