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 M1, a plurality of internal electrode layers including Cu, and an interface layer including the element M1 in at least a portion of an interface with the plurality of internal electrode layers. Element M1 is an element that has a binding energy between CZ and Cu via the element M1 of less than or equal to −9.8 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 m1 of an amount of the element M1 to an amount of the Zr in the interface layer is 0.03≤m1≤0.25.
