Laminated ceramic electronic component and circuit board

A laminated ceramic electronic component includes: a ceramic body having a plurality of internal electrodes laminated in a first axis direction and an end surface perpendicular to a second axis orthogonal to the first axis, the plurality of internal electrodes being alternately led out to the end surface; and external electrodes covering the end surfaces of the ceramic body, respectively, in which each external electrode includes: a base film formed on a corresponding end surface of the end surfaces and connected to the plurality of internal electrodes led out to the corresponding end surface; a first Ni film formed on the base film; a second Ni film formed on the first Ni film; a surface layer film formed on the second Ni film; and a metal film that is formed between the first Ni film and the second Ni film and contains, as a main component, a metal having a lower Young's modulus than that of Ni. 本发明提供一种层叠陶瓷电子部件，包括：陶瓷体，其具有在第一轴方向上层叠的多个内部电极和垂直于与第一轴正交的第二轴的端面，多个内部电极交替地引出到端面；以及外部电极，其分别覆盖陶瓷体的端面，其中，每个外部电极包括：底膜，其形成于
