description Cathode electrode part 5 of flat plate-like element 1 is joined with cathode com terminal 7 with a conductive adhesive or the like. Element mounting part 6 a of anode terminal 6 is provided with a pair of joint parts 6 b for wrapping anode electrode part 4 from both sides. The tips of joint parts 6 b and anode electrode part 4 are joined by laser welding such that the ratio (w/d) of the width (w) of each tip of joint parts 6 b and the diameter (d) of the welding trace to be welded is 0.5 to 1.5, and more preferably, 0.5 to 1.25 for providing low ESR means for concentrating the quantity of heat at the time of welding on welding parts 6 c without escape. Therefore, a stable welded state is obtained, so that the ESR is improved for achieving low ESR of the solid capacitor.
