ABSTRACT:
A solid electrolytic capacitor manufacturing method includes a process of removing a roughened surface layer (10a′) from a distal portion (13) of a metal member (10) and from part of an intermediate portion (12) adjacent to the distal portion (13), a process of forming a resist (40) on the distal portion (13) and the intermediate portion (12) of the metal member (10), a process of forming a conductive polymer layer (30) of a conductive polymer on a proximal portion (11) of the metal member (10), and a process of removing a resist (40′) and a surface layer portion (13′) of the metal member (10) from the distal portion (13) of the metal member (10).
