Abstract:
A manufacturing method of solid electrolytic capacitor comprising the steps of:(a) supplying a band metal having a central part in a width direction and a plurality of protrusions formed at an end part in said width direction, including, opening a plurality of holes at specified intervals in a longitudinal direction of said band metal, adhering an electric insulating tape to cover said plurality of holes, and said conductive tape is adhered on said electric insulating tape; (b) forming a dielectric layer above a surface of said plurality of protrusions, (c) adhering a conductive tape to said central part, (d) forming a conductive polymer film above said plurality of protrusions, by performing electrolytic polymerization by starting polymerization from said conductive tape, (e) peeling said conductive tape from said metal, and (f) fabricating a plurality of capacitor elements by cutting off each protrusion of said plurality of protrusions, from said band metal forming said conductive polymer film.
