Beschreibung
Zusammenfassung:	A nickel-hydrogen secondary battery includes: an outer can; a sealing body including a positive electrode terminal, the sealing body sealing an opening of the outer can; an electrode group formed by placing a positive electrode and a negative electrode on top of each other with a separator therebetween and spirally winding the positive electrode and the negative electrode, the electrode group housed in the outer can along with an alkaline electrolyte; a positive electrode current collector connected to positive electrode connection edge portion protruding from one end surface of the electrode group; and a current collecting lead connecting the positive electrode current collector and the sealing body, wherein a relationship between a deformation resistance A of a material a and a deformation resistance B of a material b satisfies a relationship of A
