Abstract

A ceramic electronic part that permits identifying of the orientation of the ceramic electronic part through the use of a marker provided thereinside, and that avoids drop of reliability through inhibition of any diffusion of coloring component from the marker. Stator (101) constituting part of a trimmer condenser is disposed between ceramic sintered body (103) composed of, superimposed one upon another, multiple ceramic layers (102) and ceramic layer (102). The stator (101) includes internal conductor (104) drawn out to a side face of the ceramic sintered body (103); external conductor (105a) provided on a side face of the ceramic sintered body (103) and electrically connected to the internal conductor (104); external conductor (105b) provided on a side face of the ceramic sintered body (103) opposite to the side face provided with the external conductor (105a); and black ceramic layer (106) disposed between ceramic layers (102). The black ceramic layer (106) contains an Mn oxide and an Fe oxide in a weight ratio of 3:2 to 1:3 in terms of MnCO3 and Fe2O3, respectively. The internal conductor (104) and the black ceramic layer (106) are arranged in such a fashion that in the direction of ceramic layer (102) lamination, they substantially do not overlap each other.
