ABSTRACT:
A nickel powder with a mean particle size of 0.05 to 1.0 μm, the nickel powder having a thin oxidized layer of nickel on a surface thereof, an oxygen content of 0.3 to 3.0 wt. % and a carbon content of 100 ppm or less per specific surface area of 1 m2/g of the powder, in a weight proportion of carbon to the nickel powder of unit weight. When the powder is used for a conductive paste for forming inner electrode layers of a multilayer electronic component, it enables a decrease in the residual carbon amount after a binder removal process, thereby making it possible to obtain a multilayer ceramic electronic component excellent electrical characteristics and high reliability in which electrode layers excelling in continuity are formed without decreasing the strength and electrical characteristics of the electronic component or creating structural defects.
