PROBLEM TO BE SOLVED: To suppress a crack while securing a desired electrostatic capacitance.SOLUTION: A multilayer ceramic capacitor C1 comprises: an element assembly 3; terminal electrodes 5 and 6 that are parallelly disposed in an inner part of the element assembly 3 so as to be faced each other in a lamination direction at an equivalent interval; and a plurality of inner electrodes 7 to 10. A length T of the element assembly 3 in an X-direction is longer than a length L of the element assembly 3 in a Z-direction and is equal to or less than a length W of the element assembly 3 in a Y-direction. A length W1 of the inner electrodes 7 to 10 in the Y-direction is longer than a length L1 of inner electrodes 7 to 10 in the Z-direction. The element assembly 3 includes: a plurality of opposite polarity facing areas 20A formed between the inner electrodes 7 and 9 which are faced each other; and a plurality of same polarity facing areas 20B formed between the inner part electrodes 7 which are faced each other through the inner part electrode 8 and between the inner part electrodes 9 which are faced each other through the inner part electrode 10. The opposite polarity facing areas 20A and the same polarity facing areas 20B are alternately positioned in the lamination direction.SELECTED DRAWING: Figure 3 【課題】所望の静電容量を確保しつつ、クラックを抑制する。【解決手段】積層セラミックコンデンサＣ１は、素体３と、素体３の内部において、互いに対向するように積層方向に同等の間隔で並置された端子電極５，６と、複数の内部電極７〜１０と、を備える。素体３のＸ方向での長さＴが、素体３のＺ方向での長さＬより長く、且つ、素体３のＹ方向での長さＷ以下である。内部電極７〜１０のＹ方向での長さＷ１が、内部電極７〜１０のＺ方向での長さＬ１よりも長い。素体３は、互いに対向する内部電極７，９との間に形成された複数の異極性対向領域２０Ａと、内部電極８を介して互いに対向する内部電極７同士の間と内部電極１０を介して互いに対向する内部電極９同士の間とにそれぞれ形成された複数の同極性対向領域２０Ｂと、を含む。異極性対向領域２０Ａと同極性対向領域２０Ｂとは、積層方向で交互に位置している。【選択図】図３
