Abstract
A metal powder is formed by the steps of preparing a reducing agent solution, preparing a mixed metallic salt solution by dissolving a nickel salt and a copper salt in a solvent, and mixing the reducing agent solution and the mixed metallic salt solution so that the copper salt is reduced to precipitate copper particle nuclei and then the nickel salt is reduced to precipitate nickel around the copper particle nuclei. A metal power produced by this production method, a conductive paste containing the metal powder and a monolithic ceramic electronic component in which internal electrodes are formed using the conductive paste are also disclosed.
