Zusammenfassung:To provide a multilayer ceramic electronic component hard to be adversely influenced by hydrogen.SOLUTION: A multilayer ceramic electronic component comprises a ceramic substrate, and an external electrode. The ceramic substrate comprises a plurality of internal electrodes stacked on one another in a uniaxial direction, and an end face extending along a plane parallel to the uniaxial direction. The external electrode has an inner layer part and an outer layer part. The inner layer part contains Cu as a chief ingredient, and an additive ingredient containing at least one element selected from the group consisting of Nb, Hf, Ta, W, and Pt, or contains Ni as a chief ingredient, and an additive ingredient containing at least one element selected from the group consisting of V, Cr, Mn, Zr, Nb, Mo, Ru, Hf, Ta, W, and Pt.SELECTED DRAWING: Figure 2 【課題】水素による悪影響を受けにくい積層セラミック電子部品を提供する。【解決手段】積層セラミック電子部品は、セラミック素体と、外部電極と、を具備する。セラミック素体は、一軸方向に積層された複数の内部電極と、一軸と平行な平面に沿って延びる端面と、を有する。外部電極は、内層部と外層部とを有する。内層部は、Cuを主成分とし、Nb,Hf,Ta,W,Ptからなる群から選択される少なくとも1つで構成される添加元素を含むか、或いは、Niを主成分とし、V,Cr,Mn,Zr,Nb,Mo,Ru,Hf,Ta,W,Ptからなる群から選択される少なくとも1つで構成される添加元素を含む。【選択図】図2
