Multilayer electronic component with controlled Sn diffusion in internal electrode

A multilayer electronic component comprising:

• a body including a plurality of dielectric layers and an internal electrode including a conductive material;
• and
• an external electrode disposed on the body and connected to the internal electrode,
• wherein the internal electrode includes a Sn diffusion portion including Sn in a region connected to the external electrode, and
• a layer of the external electrode that contacts the body does not include the Sn diffusion portion.

A multilayer electronic component comprising:

• and
• an external electrode disposed on the body and connected to the internal electrode,
• wherein the internal electrode includes a Sn diffusion portion including Sn in a region connected to the external electrode, and
• an atomic ratio of the Sn to the conductive material in the Sn diffusion portion decreases in an inward direction of the body from a point where the internal electrode and the external electrode are in contact,
• wherein the atomic ratio of Sn to the conductive material is 30% or more at 1 μm.
