Abstract

In a capacitor element of a solid electrolytic capacitor, a solid electrolytic layer has an edge portion near a root of a lead-out portion. An anode terminal is connected to the lead out portion at a position away from the root of the lead out portion. An ion trapping member includes a first resin and an ion trapping agent dispersed in the first resin. The ion trapping member covers the whole periphery of at least a part of the lead out portion directly or via the dielectric layer between the edge portion of the solid electrolytic layer and the anode terminal. An external insulation member includes a second resin having a high affinity for the first resin. The external insulation member envelops the capacitor element and covers at least a part of the ion trapping member, a part of the anode terminal and a part of a cathode terminal.
