Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a power storage element in which an electrode is inhibited from being bent.SOLUTION: The power storage element includes an electrode having a foil-shaped electrode substrate and an active material layer overlapped on the electrode substrate to include a particle-shaped active material, and a positive electrode in which the particle diameter D50 and the particle diameter D90 of the active material satisfy a relation expression of 0.39≤the particle diameter D50/(the particle diameter D50+the particle diameter D90)≤0.43 (the particle diameter D50 is a particle diameter at which volume integration in a particle distribution is 50%; the particle diameter D90 is a particle diameter in which volume integration in a particle distribution is 90%). The active material is lithium metal composite oxide (0
