Abstract
A method of manufacturing a laminated body in a raw state for a laminated ceramic capacitor, which includes dielectric ceramic layers containing a dielectric ceramic raw material powder for and internal electrodes, in which a heat treatment 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 BaTiOsystem as its main constituent and contains Re (Re is at least one selected from Sc, Y, La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu) as an accessory constituent, in which the content of Re is 0.3 to 3 parts by mol with respect to 100 parts by mol of the main constituent.
