Abstract
A target for sputtering which enables to attain high rate film-formation of a transparent conductive film suitable for a blue LED or a solar cell. A oxide sintered body includes an indium oxide and a cerium oxide, and one or more oxide of titanium, zirconium, hafnium, molybdenum and tungsten. The cerium content is 0.3 to 9% by atom, as an atomicity ratio of Ce/(In+Ce+M), the M element content is equal to or lower than 1% by atom, as an atomicity ratio of M/(In+Ce+M), and the total content of cerium and the M element is equal to or lower than 9% by atom, as an atomicity ratio of (Ce+M)/(In+Ce+M). The oxide sintered body has an InOphase of a bixbyite structure has a CeOphase of a fluorite-type structure finely dispersed as crystal grains having an average particle diameter of equal to or smaller than 3 μm.
