Abstract:
1. A solid electrolytic capacitor comprising: a laminated body having a plurality of dielectric-coated valve action metal sheets joined together and defining a gap therebetween, each of the plurality of dielectric-coated valve action metal sheets each including a valve action metal base having a cathode layer part and a dielectric coating covering a surface of the valve action metal base at at least the cathode layer part, and wherein at least one of the plurality of dielectric-coated valve action metal sheets has an anode lead part, and adjacent valve action metal bases of the plurality of dielectric-coated valve action metal sheets are electrically and directly joined together in the cathode layer parts by a respective first joint; a solid electrolyte layer covering an outer surface of the laminated body at the cathode layer parts and extending into the gaps between the plurality of dielectric-coated valve action metal sheets; and a respective conductive base provided in the gaps between the plurality of dielectric-coated valve action metal sheets.
