A multilayer electronic component including: a body including a dielectric layer and internal electrodes; and external electrodes disposed outside the body and connected to the internal electrodes, wherein 1.5≤Hfs/Hfc≤5.0 when the internal electrode includes hafnium (Hf), Hfc indicates an average Hf content (at %) in a center of the internal electrode, and Hfs indicates an average Hf content (at %) in the internal electrode, measured from the center of the internal electrode to an interface thereof in contact with the dielectric layer.

Multilayer electronic component

A multilayer electronic component includes a body including a capacitance forming portion including a dielectric layer and internal electrodes alternately disposed with the dielectric layer in a first direction and a cover portion disposed on one surface and the other surface of the capacitance forming portion in the first direction, and external electrodes disposed on the body, wherein a secondary phase including Al is disposed at an interface between the internal electrode and the dielectric layer, and the ratio of an area occupied by the secondary phase to an area of the capacitance forming portion is 0.03% or more and 0.40% or less.

A multilayer electronic component includes a body including a plurality of dielectric layers, a side margin portion disposed on the body, and external electrodes disposed on the body. The body includes an active portion having internal electrodes alternately arranged with the dielectric layer interposed therebetween in the first direction and a cover portion disposed on both end surfaces of the active portion in a first direction, the active portion. The cover portion, and the side margin portion include molybdenum (Mo). A Mo content in an interfacial portion, a region of the active portion, adjacent to one of the cover portion or the side margin portion, is higher than a Mo content in a central portion of the active portion. A Mo content in the one of the cover portion and the side margin portion is higher than the Mo content in the interfacial portion.

A multilayer electronic component includes a body including a dielectric layer and an internal electrode alternately stacked therein in a stacking direction; and an external electrode disposed on the body and connected to the internal electrode. The internal electrode includes 94.0 to 99.6 wt % of Ni and 0.4 to 6.0 wt % of Cu.
