A nickel ultrafine powder which is characterized by having an average particle diameter of 0.2 to 0.6 µm and containing coarse particles whose particle diameter is larger than 2.5 times the average particle diameter in an amount less than 0.1% in terms of number-size distribution. It is produced from nickel chloride vapor by reduction with hydrogen in the gas phase. It gives thin internal electrodes (which contributes to high capacity) with only a few short circuits across them.
