PROBLEM TO BE SOLVED: To provide a method for preparation of nickel powder suitable for being contained as a conductive component in a conductive paste used for forming an internal electrode of a laminated ceramic capacitor. SOLUTION: The nickel powder is obtained by preparing a nickel salt solution containing copper ions, preparing a hydrazine compound solution, adding an organic compound which is composed of N, C, O and H and has an OH group in the moleculen into a nickel salt solution and/or the hydrazine compound solution, then mixing the nickel salt solution and the hydrazine compound solution and subjecting the mixture to oxidation reduction reaction. The nickel powder of a grain size 100 to 300 nm can be obtained while suppressing the variation in the grain size and having good reproducibility. COPYRIGHT: (C)2005,JPO&NCIPI
