Abstract
A solid electrolytic capacitor that includes an element laminate having a first end face and a second end face, a first external electrode on the first end face, and a second external electrode on the second end face. In the element laminate, a first layer and a second layer are stacked. The first layer has a valve-action metal substrate, a dielectric layer on a surface thereof, and a solid electrolyte layer on the dielectric layer. The second layer contains a metal foil. The first layer and the second layer are bonded by an adhesive layer containing a conductive adhesive layer and an insulating adhesive layer that surrounds an outer perimeter of the conductive adhesive layer. The adhesive layer includes a notched part that extends from the first end face or the second end face to the conductive adhesive layer.
