Abstract
A solid electrolytic capacitor of the present invention includes a capacitor element having an anode member, a dielectric member, and a cathode member; an anode terminal attached to the anode member; a cathode terminal attached to the cathode member; and a housing for covering an outer periphery of the capacitor element, the anode terminal and the cathode terminal being each at least partly exposed from an undersurface of the solid electrolytic capacitor, the anode terminal having a projection formed by rolling using a roll having a large diameter portion and a small diameter portion, and being connected to the anode member at the projection.
