Abstract
A solid electrolytic capacitor comprises insulating substrate having an upper surface and a lower surface, a capacitor element disposed on the upper surface, a positive electrode lead-out structure, a negative electrode lead-out structure, and an exterior body configured to cover the capacitor element on the upper surface. The capacitor element has a positive electrode member, a negative electrode member, and a dielectric member. The positive electrode lead-out structure has a positive electrode terminal formed on the lower surface of the insulating substrate and is electrically connected to the positive electrode member. The negative electrode lead-out structure has a negative electrode terminal formed on the lower surface of the insulating substrate and is electrically connected to the negative electrode member. The insulating substrate has a step portion made up of a recessed surface formed by recessing the upper surface and a projected surface formed by projecting the lower surface.
