Abstract
The present invention provides a metallic powder which exhibits superior sintering properties in a production of multilayer ceramic capacitors, and exhibits superior dispersion characteristics in forming of conductive pastes, thereby preventing delamination. Metallic powder produced by bringing a metallic chloride gas into contact with a reducing gas in a reducing temperature range is subjected to a surface treatment by a nonionic surfactant in a wet or dry process to obtain final metallic powder.
