A manufacturing method for a solid electrolytic capacitor of the present invention includes producing a terminal frame having aligned therein unit terminal areas each including an anode terminal portion and a cathode terminal portion, placing a rod-like piece on a surface of the terminal frame across a plurality of aligned anode terminal portions, and fixing the rod-like piece to the terminal frame by welding. Thereafter, a solid electrolytic capacitor is provided through a placement of a capacitor element, charge of a mold resin, and a cutting process.
