The covering layer covers the first surface and includes a first outer surface that is not exposed to the oxidizing atmosphere. At least one of the base member and the covering layer includes an exposed surface that is exposed to the oxidizing atmosphere. The surface roughness of the exposed surface is different from the surface roughness of the first surface or the first outer surface.
