Abstract
A multilayer electronic component that includes a stacked body having therein a plurality of dielectric layers including a CZ-based perovskite phase and an element M2, a plurality of internal electrode layers including Ni, and an interface layer including the element M2 in at least a portion of an interface with the plurality of internal electrode layers. Element M2 is an element that has a binding energy between the CZ-based perovskite phase and Ni via the element M2 of less than or equal to −12.3 eV by first-principles calculation using a pseudopotential method. When amounts of elements included in the dielectric layers are expressed as parts by mol, a ratio m2 of an amount of the element M2 to an amount of the Zr in the interface layer is 0.03≤m2≤0.25.
