Provided is a tantalum target, wherein, when a direction normal to a rolling surface (ND), which is a cross section perpendicular to a sputtering surface of a target, is observed via an electron backscatter diffraction pattern method, an area ratio of crystal grains of which a {100} plane is oriented in the ND is 30% or more. An object of the present invention is to provide a tantalum sputtering target in which a deposition rate can be appropriately controlled under high-power sputtering conditions. When sputter-deposition is performed using this kind of a tantalum target, it is possible to form a thin film having superior film thickness uniformity and improve the productivity of the thin film formation process, even for micro wiring.
