Abstract:
1. A thin film electrode ceramic substrate, comprising: a ceramic substrate; a plurality of anti-etching metal layers formed in a surface of the ceramic substrate; a thin film electrode pattern formed on the anti-etching metal layers; and a plating layer formed on the thin film electrode pattern, wherein the anti-etching metal layers are extant under respective edge portions of the thin film electrode pattern and extends, in the ceramic substrate, a distance away from the thin film electrode pattern, the edge portions of the thin film electrode pattern are contacted with the respective anti-etching metal layers, the anti-etching metal layers are spaced apart from each other by a predetermined distance, except in a region where the anti-etching metal layers are contacted with the respective edge portions of the thin film electrode pattern, and the ceramic substrate underlays entire bottom surfaces of the anti-etching metal layers.
