Glass ceramic substrate having electrically conductive film.

摘要

A glass ceramic substrate (1) containing mica and having an electrically conductive film (2) formed thereon includes a bonding layer (3) made of a material including at least silicon oxide, which is formed on a portion of one of the opposite surfaces of the glass ceramic substrate containing mica. The electrically conductive film is formed on the bonding layer and has a major component consisting of at least one element selected from the group consisting of alminum, tungsten, molybdenum, titanium, tantalum and chromium.
