Title:
MANUFACTURING METHOD OF LAMINATED CERAMIC CAPACITOR, AND LAMINATED CERAMIC CAPACITOR
Document Type and Number:
WIPO Patent Application WO/2011/021464
Kind Code:
A1
Abstract:
Provided is a laminated ceramic capacitor, wherein reliability is not lost even when dielectric ceramic layers and internal electrodes are made to be thinner layers. Heat treatment is conducted with a temperature profile starting from room temperature and ending at maximum temperature, and having an average temperature-rising rate of 40°C/second or more, when firing, in a raw-state, a laminated body (2), which is provided with laminated ceramic layers (3) that contain dielectric ceramic raw-material powder, and internal electrodes (4 and 5), and which is for the laminated ceramic capacitor (1). BaTiO3 is the main ingredient of the dielectric ceramic raw-material powder, and Re (Re is at least one type selected from the group consisting of Sc, Y, La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu) is contained as an accessory ingredient, with the Re content made to be 0.3-3 parts by mole for 100 parts by mole of the main ingredient.
