To provide a multilayer capacitor which can reduce cracking due to internal stress or can improve withstand voltage characteristics.SOLUTION: A multilayer capacitor includes: a main body 110 including a capacity region where at least one first internal electrode 121 and at least one second internal electrode 122 are alternately laminated in a first direction with at least one dielectric layer 111 interposed therebetween; and a first external electrode 131 and a second external electrode 132 disposed away from each other on the main body in such a manner that they are coupled to the at least one first internal electrode and the at least one second internal electrode, respectively. The main body may further include a buffer layer 140 having a Young's modulus exceeding 0 times that of the at least one dielectric layer but not higher than 50/135 times that of the dielectric layer.SELECTED DRAWING: Figure 5 【課題】内部応力によるクラック（ｃｒａｃｋ）を低減するか又は耐電圧特性を高めることができる積層型キャパシタを提供する。【解決手段】積層型キャパシタは、少なくとも一つの第１内部電極１２１と少なくとも一つの第２内部電極１２２とが少なくとも一つの誘電体層１１１を間に挟んで第１方向に交互に積層された容量領域を含む本体１１０と、少なくとも一つの第１内部電極及び少なくとも一つの第２内部電極にそれぞれ連結されるように互いに離隔して本体に配置された第１外部電極１３１及び第２外部電極１３２とを含む。本体は、容量領域に配置され、少なくとも一つの誘電体層のヤング率（Ｙｏｕｎｇ'ｓ ｍｏｄｕｌｕｓ）の０倍超（５０／１３５）倍以下のヤング率を有するバッファ層１４０をさらに含むことができる。【選択図】図５
