Abstract
A process for producing a niobium capacitor, including a step of exposing the dielectric oxide layer to a temperature of 100 to 1,400° C. is disclosed. A capacitor obtained by the production process of the present invention has excellent LC properties, and the reduction in the capacitance due to application of DC bias is small.
