Abstract
A solid electrolytic capacitor comprising a capacitor element disposed on an insulating substrate, in which a positive electrode lead-out structure electrically connected to a positive electrode member of the capacitor element comprises a first positive electrode connection member disposed on the insulating substrate, a positive electrode terminal disposed on the insulating substrate, a pillow member configured to electrically connect the positive electrode member to the first positive electrode connection member, and a positive electrode bonding member. The first positive electrode connection member has a recessed portion or a through hole. The positive electrode bonding member partially enters the recessed portion or the through hole, and is in contact with an edge of a bottom surface of the pillow member at a position above the recessed portion or the through hole, or at the nearby position.
