Abstract
A multilayer electronic component includes a body including a plurality of dielectric layers and a plurality of internal electrodes alternately disposed with the plurality of dielectric layers in a first direction, and an external electrode disposed on the body. One of the plurality of internal electrodes includes Ni and In. In the one of the plurality of internal electrodes, among points 10 nm away from an interface with one of the plurality of dielectric layers, a ratio of points at which a molar ratio of In/(Ni+In) is 0.002 or more is 70% or more, and among central points in the first direction, a ratio of points at which the molar ratio of In/(Ni+In) is 0.002 or more is 35% or less.
