Abstract

Official abstract text for this publication.

A ceramic electronic component that includes: an element body containing ceramic as main material thereof; and an identification mark on a surface of element body, wherein the element body includes: a first layer containing a specific compound containing barium and silicon; and a second layer that contains the specific compound, is interposed between the identification mark and the first layer, and has a proportion of the specific compound lower than a proportion of the specific compound in the first layer.

First claim

Opening claim text (preview).

What is claimed is: 1 . A ceramic electronic component comprising: an element body containing ceramic as a main material thereof; and an identification mark on a surface of the element body, wherein the element body comprises: a first layer containing a specific compound containing barium and silicon; and a second layer that contains the specific compound, is interposed between the identification mark and the first layer, and has a proportion of the specific compound lower than a proportion of the specific compound in the first layer. 2 . The ceramic electronic component according to claim 1 , wherein the element body contains celsian as the main material thereof, and wherein the identification mark contains alumina as a main material thereof. 3 . The ceramic electronic component according to claim 1 , wherein a thickness of the second layer is the same as or substantially the same as a maximum thickness of the identification mark. 4 . The ceramic electronic component according to claim 1 , wherein the element body comprises an electrode interposed between the first layer and the second layer. 5 . The ceramic electronic component according to claim 1 , wherein the element body contains celsian as the main material thereof. 6 . The ceramic electronic component according to claim 1 , wherein the element body contains fresnoite as the main material thereof. 7 . The ceramic electronic component according to claim 1 , wherein a first part of the identification mark is embedded in the element body. 8 . The ceramic electronic component according to claim 7 , wherein a second part of the identification mark protrudes from the surface of the element body. 9 . The ceramic electronic component according to claim 1 , wherein a thermal shrinkage rate of the identification mark is lower than a thermal shrinkage rate of the element body. 10 . The ceramic electronic component according to claim 1 , further comprising a diffusion layer between the element body and the identification mark. 11 . The ceramic electronic component according to claim 1 , wherein the specific compound is celsian.
