摘要 |
An object of the present invention is to manufacture a long transparent conductive film comprising a transparent film substrate and a crystalline indium composite oxide film formed on the transparent film substrate. The manufacturing method of the present invention includes an amorphous laminate formation step of forming an amorphous film of an indium composite oxide containing indium and a tetravalent metal on the long transparent film substrate with a sputtering method, and a crystallization step of continuously feeding the long transparent film substrate on which the amorphous film is formed into a furnace and crystallizing the amorphous film. The temperature inside the furnace in the crystallization step is preferably 170 to 220° C. The change rate of the film length in the crystallization step is preferably +2.5% or less. |
