Abstract
Composite conductive powder comprises a calcined mixture of conductive powder mainly comprising indium oxide which contains at least one member selected from the group consisting of tin oxide, titanium oxide and zirconium oxide as a dopant and conductive powder mainly comprising tin oxide which contains at least one member selected from the group consisting of antimony oxide, tantalum oxide and niobium oxide as a dopant, and a conductive film is formed from the composite, conductive powder. The composite, conductive powder and the conductive film produced from the powder permit the reduction in the amounts of materials for the ITO film, in particular, indium which is an expensive material and the composite, conductive powder can simultaneously satisfy both requirements for high transparency and high conductivity even if it is used for the formation of films through the coating technique.
