Abstract
A surface mount component includes a substrate having two main faces, and first electrodes made of a metal, such as zinc, which is unlikely to cause migration. The first electrodes are formed on most of the entire face of both main faces of the substrate. Second electrodes made of a superior bonding material, such as copper, are disposed on the first electrodes. Lead terminals are bonded to the second electrodes by a bonding material, and an external packaging material covers the surface mount component. This configuration suppresses the occurrence of migration and improves resistance to electrical breakdown.
