  • Patent number: 12205768
    Abstract: A multilayer electronic component includes a body including a capacitance formation portion including dielectric layers and internal electrodes alternately disposed in a first direction, and a cover portion disposed on both end surfaces of the capacitance formation portion, facing each other in the first direction, and having a first surface and a second surface opposing each other in the first direction, a third surface and a fourth surface connected to the first and second surfaces and opposing each other in a second direction, and a fifth surface and a sixth surface connected to the first to fourth surfaces and opposing each other in a third direction, and external electrodes disposed on the third and fourth surfaces. The internal electrodes and the dielectric layers protrude more outwardly than the cover portion in the second direction, and a groove is disposed at an end of the dielectric layer in the second direction.
