▎ 摘  要

NOVELTY - Multilayer ceramic electronic component comprises a ceramic body including dielectric layers and internal electrodes, first electrode layers arranged on the ceramic body and connected to the internal electrodes, respectively, and second electrode layers arranged on the first electrode layers, respectively, and respectively including a conductive metal including silver and palladium, carbon materials, and glass particles. An area ratio of the carbon materials in a cross-section of at least a portion of each of the second electrode layers is 1-5%. USE - Multilayer ceramic electronic component used in industries such as the communications, computing, home appliance, and automobile industries. ADVANTAGE - The multilayer ceramic electronic component has small size and implements high capacitance, improved heat and moisture resistance characteristics by including external electrodes having excellent adhesive strength and impact resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for manufacturing a multilayer ceramic electronic component, which involves: contacting a first electrode layer with a conductive paste including a conductive metal including silver (Ag) and palladium (Pd), carbon materials, and glass particle to form a second electrode layer, where the first electrode layer is arranged on a body of the multilayer ceramic electronic component, and sintering the conductive paste at a temperature of from 600-700℃ for 1-2 hours. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of a multilayer ceramic electronic component. 110Ceramic body 111Dielectric layer 112First cover portion 113Second cover portion 121, 122Internal electrode
