Abstract
A ceramic coating according to at least one embodiment of the present disclosure includes: a bond coat layer formed on a substrate; and a ceramic layer formed on the bond coat layer. The ceramic layer has a first region in contact with an interface between the ceramic layer and the bond coat layer and a second region father away from the interface than the first region from the interface. In a cross-section along a thickness direction of the ceramic layer, the number of crack intersection points at which two or more cracks intersect per unit area in the ceramic layer is larger in the first region than in the second region.
