1. A solid electrolytic capacitor comprising: a plurality of capacitor elements laminated on top of each other, the capacitor elements each including a first portion and a second portion,
wherein the first portion includes a first edge and a second edge disposed opposite to each other in a first direction and at least a portion of the first portion forms a cathode portion,
the first edge includes
a flat portion formed in a center region of the first edge, and
a portion away from the center region of the first edge and from which the second portion projects,
the second portion does not project from the flat portion, and at least a portion of the second portion forms an anode portion,
in a first subset of the plurality of capacitor elements, the first edge is positioned at one side in the first direction, and the second edge is positioned at the other side in the first direction, and
in a second subset of the plurality of capacitor elements, the first edge is positioned at the other side in the first direction and the second edge is positioned at the one side in the first direction.
