Abstract:
1. A multilayer electronic component comprising: a laminate including a plurality of insulating layers laminated to each other and a plurality of internal electrodes provided along interfaces between the insulating layers, edges of the internal electrodes being exposed at a predetermined surface of the laminate; and an external electrode provided on the predetermined surface; wherein the external electrode includes a plurality of plated films including a plated film which is directly provided on the predetermined surface of the laminate so as to electrically connect the edges of the internal electrodes exposed at the predetermined surface of the laminate; at a boundary portion between each of the internal electrodes and the plated film provided on the predetermined surface of the laminate among the plurality of the plated films, a counter diffusion layer is provided, in which a metal material in the plated film is diffused into the internal electrodes and a metal material in the internal electrodes is diffused into the plated film such that the metal material in the plated film and the metal material in the internal electrodes are both detectable in the counter diffusion layer, and extend to both sides of the internal electrodes and the plated film, and, at a side of the internal electrodes, the counter diffusion layer extends to a location spaced from the predetermined surface of the laminate by about 2 μm or more; and the metal material in the plated film is different from the metal material in the internal electrodes.
