This invention aims at providing a carbon-coated metal powder having few impurities, a narrower particle size distribution, and sintering properties particularly suitable as a conductive powder of a conductive paste for forming internal conductors in a ceramic multilayer electronic component obtained by co-firing multilayered ceramic sheets and internal conductor layers; a conductive paste containing the carbon-coated metal powder; a multilayer electronic component using the conductive paste; and a method for manufacturing the carbon-coated metal powder. The carbon-coated metal powder has specific properties in TMA or ESCA measurements. The carbon-coated metal powder can be obtained by melting and vaporizing a metallic raw material in a reaction vessel, conveying the generated metal vapor into a cooling tube and rapidly cooling the metal vapor by endothermically decomposing a carbon source supplied into the cooling tube, and forming a carbon coating film on metal nuclei surfaces in parallel with generation of the metal nuclei.

Provided is a fluid-cooled contact tip assembly that can be used in methods and systems for manufacturing objects by solid freeform fabrication, especially titanium and titanium alloy objects, where the deposition rate is increased by increasing the flow rate of electric charge through the metal wire.
