摘要： An object of the present invention is to provide a niobium powder for producing a capacitor exhibiting excellent reliability; a sintered body formed from the powder; and a capacitor including the sintered body. Even when niobium exhibiting high affinity to oxygen is employed, the niobium powder is obtained by regulating the amount of oxygen contained in the powder. By employing niobium powder which has undergone partial oxidation and partial nitridation, in which the mass ratio of the nitrogen content to the oxygen content is about 1/45 or more, a capacitor exhibiting excellent reliability can be obtained.
