Zusammenfassung:	PROBLEM TO BE SOLVED: To provide nickel powder dispersion showing excellent dispersibility when forming a conductive paste, and consequently a short circuit due to the irregularity of a surface of an internal electrode and internal defects such as delamination can be prevented when manufacturing a stacked type ceramic capacitor. SOLUTION: An organic solvent is added to an water dispersing element comprising super-fine nickel powder with an average grain size of 1 μm or less and a water solvent. After at least partially replacing the water solvent with an organic solvent, and an amine system dispersing agent is added. Subsequently, cracking treatment is performed. COPYRIGHT: (C)2005,JPO&NCIPI
