Abstract: An electronic component comprises an element body and an outer electrode. The element body has a pair of end faces opposing each other, a pair of main faces opposing each other while extending so as to connect the pair of end faces to each other, and a pair of side faces opposing each other while extending so as to connect the pair of main faces to each other. The outer electrode is formed on the end face side of the element body and covers a portion of the main and side faces adjacent to the end face. At least a surface of an electrode portion of the outer electrode located on the side face side thereof is covered with an insulating layer.

Abstract: An external electrode includes a sintered metal layer disposed on at least an end surface and a conductive resin layer disposed on the sintered metal layer. The sintered metal layer includes a first portion, a second portion, and a third portion. The first portion is disposed at a central region of the end surface. The second portion is disposed at a part of a peripheral region of the end surface, and extends to an edge portion of the end surface from the first portion. The third portion is disposed at a remaining part of the peripheral region of the end surface. The thickness of the second portion is less than that of the first portion. The thickness of the third portion is less than that of the second portion. The first portion, the second portion, and the third portion are covered with the conductive resin layer.
