ABSTRACT:
A metal layer12of aluminum or an aluminum alloy is formed on at least one side of a ceramic substrate10, and a resist14having a predetermined shape is formed on the metal layer12. Then, an etchant of a mixed solution prepared by mixing ferric chloride with water without adding any acids is used for etching and removing an undesired portion of the metal layer12to form a metal circuit12on the at least one side of the ceramic substrate10.
