Abstract: An electronic component has an element body and an external electrode arranged on the element body. The element body has a pair of end faces opposed to each other, a pair of principal faces opposed to each other, and a pair of side faces opposed to each other. The external electrode is formed so as to cover the end face and a partial region of the principal face and/or a partial region of the side face. The external electrode has a thick film electrode, a thin film electrode, and a plated layer. The thick film electrode is formed on the end face. The thin film electrode is formed so as to cover the thick film electrode and the partial region of the principal face and/or the partial region of the side face. The plated layer is formed outside the thin film electrode and contains Sn or an Sn alloy.

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.
