Power storage cell

A power storage cell, comprising:

• a wound electrode assembly which includes a first electrode, a second electrode, and a separator disposed between the first electrode and the second electrode;
• and
• a securing member for securing the wound electrode assembly so that the wound electrode assembly is maintained in a wound state, wherein
• the wound electrode assembly is configured of the first electrode, the second electrode, and the separator being wound about a winding axis,
• the wound electrode assembly includes a first end surface on one side in an axial direction in which the winding axis extend, and a second end surface on the other side in the axial direction, and
• the securing member is disposed at least on the first end surface.
