NOVELTY - Manufacture of conductor layer (13) involves sequentially forming layers (A,B) (11,12) containing titanium oxide including dopant(s) such as niobium on a substrate (10) in a heated state. The layer (A) is formed under film-forming conditions for forming a layer containing polycrystal which does not contain rutile type crystal in a single layer film-forming test. The layer (B) is formed under film-forming conditions for obtaining a layer containing polycrystal which contains rutile type crystal in a single layer film-forming test.    USE - Manufacture of conductor layer. Uses of conductor layer include but are not limited to transparent electrode of flat panel display and dye-sensitized solar cell, as transparent conductive film of organic electroluminescent display, plasma display panel (PDP), color filter, PDP optical filter, touch panel, as transparent electroconductive antistatic material, near-infrared-ray shielding film, surface reflection prevention film, electromagnetic wave shielding film, light-modulation material etc.    ADVANTAGE - The method provides high yield of conductor layer excellent in electroconductivity and transparency.    DETAILED DESCRIPTION - Manufacture of conductor layer involves sequentially forming layers (A,B) containing titanium oxide including dopant(s) on a substrate in a heated state. The layer (A) is formed under film-forming conditions for forming a layer containing polycrystal which does not contain rutile type crystal in a single layer film-forming test. The layer (B) is formed under film-forming conditions for obtaining a layer containing polycrystal which contains rutile type crystal in a single layer film-forming test. The dopant(s) included in titanium oxide is chosen from niobium, tantalum, molybdenum, arsenic, antimony, aluminum, hafnium, silicon, germanium, zirconium, tungsten, cobalt, iron, chromium, tin, nickel, vanadium, manganese, technetium, rhenium, phosphorus and bismuth. The dopant is preferably niobium and tantalum.    DESCRIPTION OF DRAWING(S) - The drawing shows the schematic view of conductor layer formed on a substrate.
