  • Solid electrolytic capacitor with porous sintered body as an anode body and manufacturing thereof
    Patent number: 10347431
    Abstract: A solid electrolytic capacitor includes a capacitor element having an anode body that is a porous sintered body having a hexahedral shape, an anode lead, a dielectric layer, and a solid electrolyte layer. One end of the anode lead is embedded into the anode body from a first surface of the anode body. The anode body includes a second surface and a third surface which are opposite to each other. The anode body has a first region including the second surface, a second region including the third surface, and a third region interposed between the first region and the second region. The third region has lower density than each of the first region and the second region. An average thickness T3 of the third region and a thickness TL of the anode lead satisfy a relationship T3<TL. A surface of the anode lead is in contact with at least one of the first region and the second region.
