摘要：
A zinc oxide transparent electroconductive oxide has been difficult to use as a substrate having a transparent electrode because the oxide, when configured as a thin film, because of increased resistivity due to air and/or moisture exposure. Though doping can inhibit increase of resistance to some extent, there has been difficulty in selecting a type and an amount of a doping substance and because doping causes high initial resistance. A substrate having a transparent electrode with stable resistivity against various environments is produced by a magnetron sputtering method using a target composed of a zinc oxide transparent electroconductive oxide containing 0.50 to 2.75% silicon dioxide by weight relative to the oxide.
