Solid electrolytic capacitor

A solid electrolytic capacitor, comprising:

• a body comprising a tantalum wire disposed on one end thereof;
• a substrate, on which the body is disposed, comprising:
• an insulating layer;
• first and second wiring layers disposed on first and second surfaces, opposing each other, of the insulating layer, each of the first and second wiring layers having an anode portion and a cathode portion;
• first and second via electrodes penetrating the insulating layer to connect the anode portions of the first and second wiring layers to each other and connect the cathode portions of the first and second wiring layers to each other, respectively;
• and
• a connection portion connecting the tantalum wire to the anode portion of the first wiring layer.

A solid electrolytic capacitor, comprising:

• a body comprising a tantalum wire disposed on one end thereof in a length direction of the body;
• a substrate disposed below the body in a thickness direction of the body, perpendicular to the length direction, and comprising an insulating layer, first and second wiring layers respectively disposed on a first surface and a second surface, facing each other, of the insulating layer, and a via electrode penetrating the insulating layer to connect the first and second wiring layers to each other;
• and
• a connection portion connecting the tantalum wire to the first wiring layer,
• wherein the first and second wiring layers do not extend onto side surfaces of the solid electrolytic capacitor, the side surfaces being defined in the length direction.
