▎ 摘  要

NOVELTY - An inner electrode includes metal powder (121) containing graphene layer (131) formed on the surface. USE - Inner electrode is used for multilayer ceramic capacitor (claimed). ADVANTAGE - The inner electrode has reduced defects such as short/tracks, thus the reliability is improved. The multilayered ceramic capacitor formed using the inner electrode has excellent reliability by minimizing the difference in shrinkage between dielectric layer and inner electrode. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of structure of metal powder including graphene layer on the surface. Metal powder (121) Graphene layer (131) Hexagonal plate shape structure (132)
