摘要:
A method for manufacturing a laminated ceramic capacitor by firing a laminated body which includes dielectric ceramic layers containing a dielectric ceramic raw material powder and internal electrodes. The firing is carried out in accordance with a temperature profile in which the average rate of temperature rise is 40° C./second or more from room temperature to a maximum temperature. The dielectric ceramic raw material powder contains a BaTiO3 system as its main constituent, and contains R (R is Sc, etc.), M (M is Mn, etc.), and Mg as accessory constituents, in which, when the total amount of the accessory constituents contained is denoted by D parts by mol with respect to 100 parts by mol of the main constituent, an the specific surface area of the main constituent is denoted by E m2/g, then D/E is 0.2 to 0.8.
