A multilayer electronic component comprising:
- a body including a dielectric layer and first and second internal electrodes alternately disposed in a first direction with the dielectric layer interposed therebetween, including first and second surfaces facing in the first direction, third and fourth surfaces connected to the first and second surfaces and facing in a second direction, and fifth and sixth surfaces connected to the first to fourth surfaces and facing in a third direction, and including a first corner connecting the third surface to each of the first, second, fifth, and sixth surfaces and a second corner connecting the fourth surface to each of the first, second, fifth, and sixth surfaces;
- a first external electrode including a first base electrode layer disposed on the third surface and extending to and disposed on at least a portion of the first, second, fifth, and sixth surfaces, a first corner electrode layer disposed at the first corner and disposed on the first base electrode layer, and a first plating layer disposed on the first corner electrode layer and disposed to contact at least a portion of the first base electrode layer on the third surface;
- and
- a second external electrode including a second base electrode layer disposed on the fourth surface and extending to and disposed on at least a portion of the first, second, fifth, and sixth surfaces, a second corner electrode layer disposed at the second corner and disposed on the second base electrode layer, and a second plating layer disposed on the second corner electrode layer and disposed to contact at least a portion of the second base electrode layer on the fourth surface,
