To provide a laminate-type electronic component which enables the increase in capacity per unit volume.SOLUTION: A laminate-type electronic component 1000' comprises: a main body 110 including dielectric layers 111 and internal electrodes 121, 122; a first external electrode 131' including a first connection part 131a', a first band part 131b' and a third band part 131c'; a second external electrode 132' including a second connection part 132a', a second band part 132b' and a fourth band part 132c'; an insulation layer 151 disposed over the first and second connection parts so as to cover the second to fourth band parts; a first plating layer 141 disposed on the first band part; and a second plating layer 142 disposed on the second band part. In the laminate-type electronic component, a first additional electrode layer 134 is disposed between the first connection part and the third face of the main body, and a second additional electrode layer 135 is disposed between the second connection part and the fourth face of the main body. The first and second external electrodes contain Cu. The first and second additional electrode layers contain Ni.SELECTED DRAWING: Figure 7 【課題】単位体積当たりの容量が向上する積層型電子部品を提供する。【解決手段】積層型電子部品１０００'は、誘電体層１１１と内部電極１２１、１２２を含む本体１１０と、第１接続部１３１ａ'、第１バンド部１３１ｂ'及び第３バンド部１３１ｃ'を含む第１外部電極１３１'と、第２接続部１３２ａ'、第２バンド部１３２ｂ'及び第４バンド部１３２ｃ'を含む第２外部電極１３２'と、第１接続部及び第２接続部上に配置され、第２～第４バンド部を覆うように配置される絶縁層１５１と、第１バンド部上に配置される第１めっき層と１４１、第２バンド部上に配置される第２めっき層１４２と、を含む。第１接続部と本体の第３面との間には第１追加電極層１３４が配置され、第２接続部と本体の第４面との間には第２追加電極層が１３５配置され、第１外部電極及び第２外部電極はＣｕを含み、第１追加電極層及び第２追加電極層はＮｉを含む。【選択図】図７
