An object of the present invention is to provide an antimony-containing niobium sintered body for a capacitor having a small specific leakage current value, an antimony-containing niobium powder for use in the sintered body, and a capacitor using the sintered body. In the present invention, an antimony-containing niobium powder having an antimony content of preferably about 0.1 to about 10 mol % and an average particle size of preferably about 0.2 to about 5 mum is used. By using this antimony-containing niobium powder, a sintered body and a capacitor are constructed.
