PROBLEM TO BE SOLVED: To provide a multilayer capacitor in which an ESL is small and which has a small size.SOLUTION: A multilayer capacitor includes: a plurality of electrostatic capacity parts in which a first inner electrode and a second inner electrode each having a different polarity and a dielectric part are laminated; a first penetration conductor that is conducted to a first inner electrode, is extended along a lamination direction of the electrostatic capacity parts, and is led to a main surface of an element body; a second penetration conductor that is conducted to the second inner electrode; a first outer part terminal electrode conducted to the first penetration conductor; and a second outer terminal electrode conducted to the second penetration conductor. Each penetration conductor is arranged so as to eliminate a magnetic field. Each electrostatic capacity part is arranged so as to be opposite to an arrangement direction of the penetration conductor. In each electrostatic capacity part, a first leading electrode that is led from the first inner electrode and is conducted to the first penetration conductor and a second leading electrode that is led from the second inner electrode and is conducted to the second penetration conductor are arranged in the first and second inner electrodes projected from the laminate direction of the electrostatic capacity parts in an almost axial symmetry.SELECTED DRAWING: Figure 1 【課題】ＥＳＬが小さく小型の積層コンデンサを提供すること。【解決手段】極性が異なる第１内部電極と第２内部電極と誘電体部とが積層された複数の静電容量部と、静電容量部の積層方向に沿って延び素子本体の主面に引き出され、第１内部電極に導通する第１貫通導体および第２内部電極に導通する第２貫通導体と、第１貫通導体に導通する第１外部端子電極と、第２貫通導体に導通する第２外部端子電極とを有し、貫通導体は磁界を打ち消すように配置され、静電容量部は貫通導体の配置方向に対向するように配置され、各静電容量部において、第１内部電極から引き出され第１貫通導体と導通する第１引出電極と、第２内部電極から引き出され第２貫通導体と導通する第２引出電極と、が静電容量部の積層方向から投影した第１内部電極および第２内部電極において、略線対称となるよう配置されている積層コンデンサである。【選択図】図１
