Abstract:
A ceramic circuit board includes a ceramic base material, a metal layer (first metal layer), and a marker portion. The marker portion is formed on the surface of the first metal layer. The surface of the metal layer (first metal layer) may be plated. When the surface of the metal layer (first metal layer) is plated, the marker portion may be formed on the plating.
