Zusammenfassung:To provide a multilayered capacitor having a reduced initial failure by delaying the occurrence of cracks due to the piezoelectric phenomenon.SOLUTION: A multilayered capacitor includes: a capacitor body including dielectric layers, a pair of first internal electrode layers and a pair of second internal electrode layers stacked with the dielectric layers interposed therebetween; and a first external electrode and a second external electrode disposed on both sides in a longitudinal direction of the capacitor body. The pair of first internal electrode layers are connected to the first external electrode and the second external electrode, respectively. The pair of second internal electrode layers are connected to the first external electrode and the second external electrode, respectively. An average length of the pair of first internal electrode layers and an average length of the pair of second internal electrode layers are different.SELECTED DRAWING: Figure 1 【課題】電歪現象によるクラック発生を遅延させて初期故障が減少した積層型キャパシタを提供する。【解決手段】一実施形態による積層型キャパシタは、誘電体層、誘電体層を間に置いて積層される一対の第1内部電極層と一対の第2内部電極層を含むキャパシタ本体、そしてキャパシタ本体の長さ方向両側に配置される第1外部電極および第2外部電極を含み、一対の第1内部電極層は、それぞれ第1外部電極および第2外部電極と連結され、一対の第2内部電極層は、それぞれ第1外部電極および第2外部電極と連結され、一対の第1内部電極層と一対の第2内部電極層は、幅方向の平均長さが互いに異なる。【選択図】図1
