Abstract

Abstract In a method of forming a transparent conductive film, an arc discharge type plasma (9) produced by arc discharging is generated in an atmosphere wherein the pressure of an atmospheric gas is 3.0 x 10<-><4> Torr or higher; the plasma (9) is converged onto a vapor deposition material (3) for forming a transparent conductive film to thereby evaporate the vapor deposition material (3), whereby said transparent conductive film is formed on a substrate (6) located above said vapor deposition material.
