Zusammenfassung:PROBLEM TO BE SOLVED: To avoid a short circuit failure when a high voltage or a large current is applied.SOLUTION: A multilayer capacitor comprises: a plurality of dielectric layers 11 in which a mixed material of an organic resin and a ceramic dielectric is included as a main component; and a plurality of inner electrodes 12 in which a metal alternately laminated with the dielectric layers 11 is included as the main component. In a part or a whole of the plurality of dielectric layers and the plurality of inner electrodes, the relationship of a thickness t1 of the dielectric layers and a thickness t2 of the inner electrodes sandwiching the dielectric layers satisfies the following relational equation: t1≥15×t2.SELECTED DRAWING: Figure 7 【課題】高電圧または大電流が印加されたときにショート故障を回避すること。【解決手段】有機樹脂とセラミック誘電体との混合材料を主成分とする複数の誘電体層11と、前記誘電体層11と交互に積層された金属を主成分とする複数の内部電極12と、を具備し、前記複数の誘電体層および前記複数の内部電極の一部または全体において、誘電体層の厚さt1と前記誘電体層を挟む内部電極の厚さt2との関係が、t1≧15×t2である積層コンデンサ。【選択図】図7
