PROBLEM TO BE SOLVED: To provide a stack penetration capacitor with smaller height, which can be easily incorporated in a board with a stable posture.SOLUTION: The length of an element 2 in a first direction D1 is smaller than the length of the element 2 in a second direction D2 and the length of the element 2 in a third direction D3. The total of the area of a printed conductor layer of a first signal terminal electrode 5 and the area of a printed conductor layer of a second signal terminal electrode 7 is larger than the area of a printed conductor layer of a ground terminal electrode 9. The thickness of a printed conductor layer of an electrode part 9a of the ground terminal electrode 9 is larger than the thickness of a printed conductor layer of electrode parts 5a and 7a of the first and second signal terminal electrodes 5 and 7. The thickness of a plating layer of the electrode parts 5a and 7a of the first and second signal terminal electrodes 5 and 7 is larger than the thickness of a plating layer of the electrode part 9a of the ground terminal electrode 9. The thickness of the electrode parts 5a and 7a of the first and second signal terminal electrodes 5 and 7 is equal to the thickness of the electrode part 9a of the ground terminal electrode 9.SELECTED DRAWING: Figure 1 【課題】低背化が図られ、容易にかつ安定した姿勢で基板に内蔵することが可能な積層貫通コンデンサを提供する。【解決手段】素体２の第一方向Ｄ１の長さは、素体２の第二方向Ｄ２の長さ及び素体２の第三方向Ｄ３の長さよりも小さい。第一信号用端子電極５の焼付導体層の面積と第二信号用端子電極７の焼付導体層の面積との合計値は、接地用端子電極９の焼付導体層の面積よりも大きい。接地用端子電極９の電極部分９ａの焼付導体層の厚みは、第一及び第二信号用端子電極５，７の電極部分５ａ，７ａの焼付導体層の厚みよりも大きい。第一及び第二信号用端子電極５，７の電極部分５ａ，７ａのめっき層の厚みは、接地用端子電極９の電極部分９ａのめっき層の厚みよりも大きい。第一及び第二信号用端子電極５，７の電極部分５ａ，７ａの厚みと接地用端子電極９の電極部分９ａの厚みは、同等である。【選択図】図１
