Abstract
A multilayer electronic component includes a body including a dielectric layer and an internal electrode, an external electrode disposed outside the body, and an insulating layer disposed on the external electrode. The external electrode is disposed to cover an exposed surface of an outermost surface of the electrode layer, and is formed to have a thickness, equal to or less than a thickness of the body, and the insulating layer is disposed to cover an end of the external electrode, to improve moisture resistance reliability.
