摘要： A laminated electronic component includes an element body formed by laminating an insulating layer and having a bottom surface used as a mounting surface, and a bottom surface electrode formed on the bottom surface of the element body and containing glass and a sintered metal. The bottom surface electrode includes a first electrode layer and a second electrode layer formed on the element body side from the first electrode layer, an edge portion of the second electrode layer is covered with an overcoat layer which is a part of the element body, the first electrode layer is laminated on the second electrode layer with the overcoat layer interposed therebetween, and a content of glass in the first electrode layer is larger than a content of glass in the second electrode layer.

摘要： 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.

摘要： Provided is a more versatile black marker composition which achieves excellent adhesion between a mark and an electronic component element body and excellent contrast of a mark regardless of the composition of the electronic component element body, the black marker composition containing borosilicate glass and a black oxide, in which a crystallization temperature of the borosilicate glass is less than 910° C., and an amount of Zn in terms of ZnO is 0.05% by mass or less based on 100% by mass of an inorganic solid content in terms of an oxide contained in the black marker composition.
