Stacked solid electrolytic capacitor

A stacked solid electrolytic capacitor having a plurality of solid electrolytic capacitor elements stacked in a stacking direction,

• wherein each solid electrolytic capacitor element comprises an anode formed of a valve action metal,
• an anode section formed on an end of the anode,
• a dielectric formed on the surface of the valve action metal and comprising an oxide of the valve action metal, and
• a cathode layer formed on the dielectric,
• the cathode layers of the plurality of stacked solid electrolytic capacitor elements being connected to each other,
• the anode sections of the plurality of stacked solid electrolytic capacitor elements being connected to each other,
• wherein a conductive layer extending in the stacking direction having a flat outside principal surface is formed on at least part of a side face of an area where the cathode layers of the solid electrolytic capacitor elements are formed,
• wherein the conductive layer is formed of a conductive paste having, as a major component, conductive particles and a resin, and is formed only on a side face area of the area where the cathode layers of the solid electrolytic capacitor elements are formed,
• wherein no conductive member is provided on the flat outside principal surface of the conductive layer, and
• wherein the conductive layer is formed in an area taking up between 1/10 or more and ½ or less of an area of a side face of the area where the cathode layers of the solid electrolytic capacitor elements are formed.
