Transparent panel heater
First Claim
1. A transparent panel heater having a transparent conductive film which is formed on a transparent substrate and which can be used as a heating surface, and a pair of metallic electrodes deposited by a wet plating process using an acidic solution for electrifying the transparent conductive film;
- said transparent panel heater comprising;
an acid-resistant transparent protective film formed on the transparent conductive film and a light-transmittable metallic electrode-underlying-layer formed on the transparent protective film, said metallic electrodes being formed on said electrode-underlying-layer by a wet plating process in an acidic solution.

Abstract
A transparent panel heater which can be used for heating a window portion of liquid crystal displays, refrigerated showcases, freezed showcases, defrosters of windshields, and the like. The panel heater has a transparent substrate, a transparent conductive film formed on the substrate, a substantially light-transmittable metallic electrode-underling-layer formed on the transparent conductive film and a pair of metallic electrodes which are provided for electrifying the conductive film and formed on the electrode-underlying-layer. The transparent conductive film is a laminate of at least one transparent thin layer made of a nitride and/or a carbide and at least one substantially light-transmittable metallic layer. The transparent conductive film and electrode-underlying-layer are preferably formed by a dry process, and the electrodes are preferably formed by a wet plating method.
