Abstract
A multilayer electronic component includes a laminate including insulating layers that are laminated to each other and 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. The external electrode includes a plated film which is directly provided on the predetermined surface of the laminate so as to electrically connect edges of the internal electrodes exposed at the predetermined surface of the laminate, and at a boundary portion between each of the internal electrodes and the plated film, a counter diffusion layer is provided, in which a metal component in the plated film and a metal component in the internal electrodes are both detectable, and extend to both sides of the internal electrodes and the plated film, and, at a side of the internal electrodes.
