A multilayer electronic component includes a body including a first internal electrode and a second internal electrode alternately disposed in a first direction with a dielectric layer interposed therebetween, and including a first surface and a second surface opposing each other in the first direction, a third surface and a fourth surface opposing each other in a second direction, and a fifth surface and a sixth surface opposing each other in a third direction. A first external electrode is disposed on the third, fourth, fifth, and sixth surfaces. A second external electrode is disposed on one or more of the first and second surfaces, and a via electrode is exposed through a surface on which the second external electrode is disposed. A ratio W/L is 0.95 or more and 1.05 or less, where L is a length of the body and W is a width of the body.
