In a laminated ceramic electronic component, a first functional portion and a second functional portion are disposed within a ceramic element body so as to be adjacent to each other along a height direction, first and second internal electrodes face each other through a ceramic layer in the first functional portion, and third and fourth internal electrodes whose number of laminated layers is different from the number of laminated layers of the first and second internal electrodes face each other through the ceramic layer in the second functional portion. A marking internal conductor is disposed on the same plane as the first internal electrode and/or the second internal electrode, a marking external conductor is disposed on the side surface of the ceramic element body so as to link a plurality of exposed marking internal conductors such that it is possible to recognize vertical directionality.
