A multilayer ceramic electronic component includes a multilayer body including first and second internal electrode layers each alternately laminated with ceramic layers and exposed at a respective end surface, first step layers on a same plane as a respective one of the second internal electrode layers and exposed at a first end surface, and second step layers on a same plane as a respective one of the first internal electrode layers and exposed at a second end surface. The first step layers each have a thickness in a height direction of the multilayer body greater at a location closer to the first main surface than the second main surface, and the second step layers each have a thickness in the height direction of the multilayer body greater at a location closer to the first main surface than the second main surface.
