1. A multilayer electronic component comprising:
a body including a dielectric layer and first and second internal electrodes alternately disposed with each other while having the dielectric layer interposed therebetween, and having first and second surfaces opposing each other in a first direction, third and fourth surfaces connected to the first and second surfaces and opposing each other in a second direction, and fifth and sixth surfaces connected to the first to fourth surfaces and opposing each other in a third direction;
a first external electrode including a first connection portion disposed on the third surface and a first band portion extending from the first connection portion onto the first and second surfaces; and
a second external electrode including a second connection portion disposed on the fourth surface and a second band portion extending from the second connection portion onto the first and second surfaces,
wherein the first external electrode includes a first electrode layer connected to the first internal electrode, a first resin layer including separated, in a cross-section of the body taken along the first and second directions, first and second portions respectively in contact with the first and second surfaces, and a first conductive resin layer disposed on the first electrode layer and extending to the first resin layer,
the second external electrode includes a second electrode layer connected to the second internal electrode, a second resin layer including separated, in the cross-section of the body taken along the first and second directions, first and second portions respectively in contact with the first and second surfaces, and a second conductive resin layer disposed on the second electrode layer and extending to the second resin layer, and
L1′≥L1 when L1 indicates a second-directional size of the first resin layer in the first band portion, and L1′ indicates a second-directional size of the first conductive resin layer in the first band portion.
