摘要:
The present invention relates to a method of manufacturing a multilayer ceramic capacitor, comprising the steps of: (a) alternately layering internal electrodes and ceramic green sheets containing a ceramic material comprising barium titanate to form a laminated body; (b) sintering the laminated body to obtain a sintered body; and (c) forming an external electrode on end faces of the sintered body to obtain a multilayer ceramic capacitor. The barium titanate has a diffraction line derived from (002) plane and a diffraction line derived from (200) plane in an X-ray diffraction chart. The ratio I(200)/Ib of peak intensity I(200)at 2θ(200) to diffraction intensity Ib at a midpoint angle between peak angle 2θ(002) of the diffraction line derived from the (002) plane and peak angle 2θ(200) of the diffraction line derived from the (200) plane is 2 to 10. The product r·Sa of mean particle size r (μm) of the barium titanate and specific surface area Sa (m2/g) is 1 to 2.
