Abstract
A Cr trapping agent is disposed so that it contacts with constituting components of the substrate containing Cr. As the Cr trapping agent, an element or Ag is used, wherein the element is stronger in basicity than alkali metals or alkaline earth metals. Since the Cr trapping agent prevents transfer of Cr towards the alkali metals or alkaline earth metals, the reaction between Cr and alkali metals or alkaline earth metals is prevented.
