Document Type and Number:
Japanese Patent JP5737388
Kind Code:
B2
Abstract:
A first paste film containing a metal powder and non-vitreous inorganic oxide is formed on a glass ceramic green sheet, and a second paste film containing a metal powder is formed on the first paste film to cover at least the edge portion of the first paste film. Then the glass ceramic green sheet and the first and second paste films are fired. As a result, a surface electrode is obtained, and then a plating layer is formed on the surface electrode. The second paste film contains less non-vitreous inorganic oxide than the first paste film and the abundance ratio of the non-vitreous inorganic oxide in the surface electrode is lower in a region bordering the plating layer than in a region bordering the glass ceramic layer at least in an edge portion of the surface electrode.
