1. A laminated ceramic electronic component comprising:
a laminated body comprising:
ceramic layers and electrode layers which are alternately laminated, and
a pair of end portions;
a pair of external electrodes, each of the pair of external electrodes located at each of the pair of end portions; and
an intermediate electrode comprising:
a first end being in direct contact with at least one of the electrode layers, and
a second end being in contact with one of the external electrodes, such that the intermediate electrode physically separates each of the electrode layers and the external electrodes,
wherein the intermediate electrode contains a conductive carbon material that is at least one selected from the group consisting of a conductive polymer, carbon black, carbon nanotube, carbon nanofiber, and graphite, and
wherein the intermediate electrode contains 20 vol % or more of the conductive carbon material.
