CARBON-COATED METAL POWDER, CONDUCTIVE PASTE CONTAINING CARBON-COATED METAL POWDER AND MULTILAYER ELECTRONIC COMPONENT USING SAME, AND METHOD FOR MANUFACTURING CARBON-COATED METAL POWDER
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.

CAPACITOR AND MODULE
The capacitor includes a dielectric body portion including ceramic layers and internal-electrode layers laminated in an alternating manner, and a cover portion provided in a periphery of the dielectric body portion. The cover portion includes pores. A part of the cover portion located in a position in a direction perpendicular to a lamination direction of the ceramic layers and the internal-electrode layers is a side surface cover portion. When the side surface cover portion is divided into three equal regions in a width direction, the regions being a dielectric body portion-side region, a central region, and a surface-side region, the number of the pores is higher in the dielectric body portion-side region than in the central region and the surface-side region.
Film capacitor
A film capacitor that includes first and second dielectric films, first and second inner electrodes, and first and second outer electrodes. The first inner electrode includes a first connection portion, a first main electrode portion joined to the first connection portion and thinner than the first connection portion, and a first thin portion extending from the first main electrode portion and thinner than the first main electrode portion. The second inner electrode includes a second connection portion and a second main electrode portion joined to the second connection portion and thinner than the second connection portion. The first main electrode portion opposes the second main electrode portion across the first dielectric film. The second connection portion includes a reduction region having a thickness that decreases from the second connection portion toward the second main electrode portion. The first thin portion opposes the reduction region across the first dielectric film.
