Abstract: A multilayer electronic component includes a body including a dielectric layer and first and second internal electrodes, first and second external electrodes respectively disposed on opposing surfaces of the body and connected to the first internal electrode, and a third external electrode disposed on the body, disposed between the first and second external electrodes and connected to the second internal electrode. One of the first and second external electrodes includes a first conductive resin layer, the first conductive resin layer includes first conductive particles including at least one of a first metal particle and a first intermetallic compound, and a first resin, and a ratio N1/N2 is 17% or more, in which N1 is the number of particles having a Feret diameter of 14 ?m or more, among the first conductive particles, and N2 is a total number of first conductive particles.

Abstract: The present invention relates to a monoclonal antibody binding specifically to the p60 protein of Listeria monocytogenes, a hybridoma cell producing the monoclonal antibody, a test kit comprising the monoclonal antibody, and a method for detecting Listeria monocytogenes using the monoclonal antibody. The inventive monoclonal selectively recognizes only Listeria monocytogenes, so that the use of such an antibody allows for rapid determination of the food contamination with these bacteria pathogenic to humans.
