1. A power storage device comprising:
an electrode; and
an exterior body,
wherein the electrode and the exterior body each have a circular shape and overlap with each other,
wherein an outer periphery of the exterior body comprises a first side, a second side, and a vertex,
wherein the vertex is a cross point of the first side and the second side,
wherein a distance between an outer periphery of the electrode and the vertex is larger than a distance between the outer periphery of the electrode and a part of the first side,
wherein the outer periphery of the electrode comprises a first region having a curved shape in a plan view, and
wherein the electrode and the exterior body each have a shape protruding toward an outside of the power storage device.
 
8. A power storage device comprising:
an electrode; and
an exterior body,
wherein the electrode and the exterior body each have a circular shape and overlap with each other,
wherein an outer periphery of the electrode comprises a first region having a curved shape in a plan view,
wherein an outer periphery of the exterior body comprises a second region,
wherein the second region is protruding toward an area inside the first region in the plan view, and
wherein the electrode and the exterior body each have a shape protruding toward an outside of the power storage device.
