Abstract

Disclosed is a method for forming a dielectric coating film on the surface of a microporous valve active metal material by a chemical conversion treatment. A method for manufacture of solid electrolytic capacitor, comprising a step of performing a thermal treatment and, prior to and subsequent to the step, a step of chemically converting in an electrolytic solution containing an adipate salt, wherein each of the steps is performed once or more times; and a solid electrolytic capacitor manufactured by the method. It becomes possible to provide an oxide coating film for use as a dielectric body in a solid electrolytic capacitor, which has an improved stability, a reduced deterioration in leakage current property, and improved yield and reliability.
