ABSTRACT:
An oxide sintered body is composed mainly of indium and containing tungsten, has a resistivity of no more than 1 kΩcm. The tungsten content in terms of the W/In atomic ratio is preferably at least 0.001 and no more than 0.17. The oxide sintered body comprise mainly a bixbyite structure indium oxide crystal phase containing tungsten in a solid solution and/or an indium tungstate compound crystal phase, with no tungsten oxide crystal phase present, whereby an oxide sintered body for use as a sputtering target is provided, for an oxide based transparent conductive film with low resistance and excellent transmission characteristics for the infrared light region.
