Ceramic element and method of manufacturing the same

摘要

A ceramic element includes: a ceramic body (18); a first coating layer (14) disposed on a first part of a front surface of the ceramic body; and a second coating layer (16) disposed on a second part of a back surface of the ceramic body. The first coating layer continuously extends from the front surface to a first region of a side surface of the ceramic body, the side surface being a machined surface, and the first region being a front side region of the side surface. The second coating layer continuously extends from the back surface to a second region of the side surface of the ceramic body, the second region being a back side region of the side surface. In the machined surface, one of the first and second coating layers is disposed at least partially on the other of the first and second coating layers.
