Miao® Yang attacker, The inner conductor 5〇4 is disposed between the layers of the ceramic layer 502, and/or the outer surface of the ceramic sintered body 503; and the outer conductors 505a and 505b are formed on the side of the ceramic sintered body. . Further, a metal rotor 507 is disposed on the upper portion of the stator 5〇1, and terminal electrodes 5〇8 and projections 5〇9 formed in the lower portion of the rotor 5〇7 are in contact with the upper surface of the ceramic sintered body 503. The rotor 5〇7 is covered with a metal cover 511 via a spring washer 51〇. A terminal 512 formed by partially extending the metal cover 511 is electrically connected to the outer conductor 5A on the side of the ceramic sintered body 503. The metal cover 511 is provided with a through hole 513 through which the actuator is inserted into the driver groove 514 formed in the rotor 5?. In the trimmer capacitor 500, a capacitance is formed between the inner conductor 504 and the terminal electrode 5〇8, but if the ceramic sintered body is reversed, the desired capacitance cannot be formed. Therefore, the ceramic sintered body 5〇3 and the metal are bonded. At the time of the cover 511, it is necessary to have a marker for identifying the upper and lower sides of the ceramic sintered body 5〇3. In order to solve the above problem, Patent Document 1 suggests that a ceramic containing Ti〇2 and Mn3〇4 is printed between the layers of the ceramic layer 113712.doc 1313015, and sintered to form a mark, thereby identifying the ceramic electronic component above and below.

For this reason, compared with the other portions φ, the portion where the mark overlaps with the internal electrode becomes thicker, which causes a structural defect of the ceramic sintered body. Further, when it is supplied for drying, the coloring component diffuses from the mark to the ceramic layer and reaches the internal electrode, which may cause deterioration in the reliability of the ceramic electronic component. In addition, in order to suppress the diffusion of the coloring component, it is conceivable to form a mark on the surface of the ceramic sintered body after the ceramic sintered body is produced. However, in this case, as disclosed in Patent Document 1, problems such as mounting failure may occur. The present invention is for solving the above problems, and an object thereof is to identify the directivity of a ceramic electronic component by forming a mark inside the #☆, and suppress the diffusion of the colored component from the mark, and provide a reliability without lowering the reliability.

On the other hand, in the samples i to 3: since the Μη component was excessively added, the evaluation on the permeability and the deflection was not good. In terms of trial and error, the color of the color was too strong due to the excessive addition of the component. Based on this, the evaluation of 'permeability' is not good. [Second Experimental Example] / In the present experimental example, the influence of the formation position of the black core layer was examined. Hundreds of first, prepare Ca〇-La2〇3_Ti〇2_Nd2〇3 series ceramic powder (green after sintering), and Ba0_Ti〇2_La2〇3_Nd2〇3 series ceramic powder (stained after baking) [as a ceramic powder] In the same manner as in the experimental example, two kinds of ceramic green sheets having a thickness of 2 μm were produced using such ceramic powder.

As shown in Fig. 6, the unsintered ceramic laminate 4〇3 contains the ceramic paste 40黑色 for the black ceramic layer therein; however, since the internal conductor is not related to the experiment, it is not formed. In Fig. 6, each layer of the ceramic green sheet is not illustrated. As shown in Fig. 6, in the thickness direction of the unsintered ceramic laminate 403, it is assumed that the distance from the upper surface 403a to the ceramic paste 4〇6 for the black ceramic layer is Χ(μιη), and the ceramic for the black ceramic layer is used.
