The present invention provides a sputtering target suitable for producing an amorphous transparent conductive film which can be formed without heating a substrate and without feeding water during the sputtering; which is easily crystallized by low-temperature annealing; and which has low resistivity after the crystallization. The Invention is designed to eliminate the backbreaking job of installing and un-installing equipment each boating season. The first connector has a flange portion that extends outwardly from an outer periphery of the first connector and has a first through hole.
