1. A multilayer electronic component comprising:
a body including an active portion in which dielectric layers and internal electrodes are alternately disposed in a first direction, an upper cover portion disposed on an upper surface of the active portion in the first direction, and a lower cover portion disposed on a lower surface of the active portion in the first direction, and including first and second surfaces opposing each other in the 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; and
external electrodes including connection portions disposed on the third and fourth surfaces and band portions extending from the connection portions onto portions of the first and second surfaces, and including electrode layers disposed on the body and conductive resin layers disposed on the electrode layers,
wherein the upper cover portion and the lower cover portion include dummy electrodes, and, in a cross-section of the body taken in the first and second directions at a center of the body in the third direction, a line along which the band portion of the conductive resin layer is in contact with the first surface is d, an area of an isosceles right triangle, in which d is a base and an extension line extending from an end of the band portion of the electrode layer by a length of d in a direction perpendicular to the first surface is a height, is K1, a ratio of an area occupied by the dummy electrodes and the internal electrodes in K1 to K1 is K2, and K2 is 20% or more.
