Abstract
A ceramic substrate is irradiated in an atmospheric air with a laser having a power density of 1.0×10-1.0×10W/cmfor an action time on an irradiation area of 1.0×10-1.0×10s to roughen a surface of the ceramic substrate, as well as to form an oxide layer on a roughened surface. A thermal sprayed coating formed on the ceramic substrate sufficiently adheres to the ceramic substrate via the oxide layer.
