Abstract
A solid electrolytic capacitor includes: an insulating substrate; a capacitor element; a positive electrode lead-out structure; and a negative electrode lead-out structure. The positive electrode lead-out structure includes: a positive electrode terminal formed on the insulating substrate; a first positive electrode connection member formed on the insulating substrate; a second positive electrode connection member electrically connecting the first positive electrode connection member to the positive electrode terminal; and a pillow member configured to electrically connect the capacitor element to the first positive electrode connection member. The first positive electrode connection member has a recessed portion or a through hole. The recessed portion or the through hole overlaps an edge of a bottom surface of the pillow member having a first end of the recessed portion or the through hole disposed outside the edge and a second end of the recessed portion or the through hole disposed inside the edge.
