An outer insulation member made of a first resin packs a part of an anode terminal. The packed part of the anode terminal has a predetermined section. All surfaces of the predetermined section consist of a front surface, a back surface and edges connecting between the front surface and the back surface. The front surface includes a connection area. An anode lead wire is connected to the connection area while being not connected to the anode terminal other than the connection area. The all surfaces of the predetermined section are completely covered with a mask layer made of a second resin except for the connection area. The second resin is different from the first resin in at least one of composition thereof, content of an inclusion, size of an inclusion and shape of an inclusion.

Solid electrolytic capacitor

A solid-state electrolytic capacitor including a stacked body of a solid-state electrolytic capacitor element unit and an electrode conversion board. The unit includes two kinds of solid-state electrolytic capacitor elements. Each of first kind of solid-state electrolytic capacitor elements uses an anode body having a total thickness of an aluminum foil of 350 μm and a residual core thickness, i.e., the total thickness minus the thickness of an etched layer, is 50 μm. A second kind of solid-state electrolytic capacitor element provided on the mounting surface side uses an anode body having a total thickness of an aluminum foil of 150 μm and a residual core thickness is 50 μm. The electrode conversion board includes external anode and external cathode terminals that are arranged in a checkered manner and also includes, on the side opposite to the board, anode electrode and cathode electrode plates.
