A multilayer ceramic electronic component includes a multilayer body including layered ceramic layers and layered inner electrode layers and having a rectangular parallelepiped shape, and outer electrodes covering both end surfaces of the multilayer body and extending from both end surfaces to cover at least a portion of a first main surface of the multilayer body. The multilayer ceramic capacitor includes an insulating layer continuously extending from a ceramic layer at the first main surface of the multilayer body so as to cover end edge portions of both the outer electrodes located on the first main surface of the multilayer body, and t2>t1 is satisfied.
