BASE MATERIAL WITH AUXILIARY WIRING AND METHOD FOR MANUFACTURING SUCH BASE MATERIAL

摘要

Provided are a base material, which has high resistance to an etchant for a transparent conductive film and has an auxiliary wiring on the transparent conductive film, and a method for manufacturing such base material. The base material with the auxiliary wiring is provided with the transparent conductive film on the base material; and the auxiliary wiring including a patterned base layer, a conductor layer having Al or an Al alloy as a main ingredient, and a cap layer in this order, on the transparent conductive film. The base material is characterized in that an outer surface plane of the conductor layer is an Al oxide layer, an Al alloy oxide layer, a layer having chromium oxide as a main ingredient or a layer having phosphate as a main ingredient.
