Claim 14:
15. The electrode according to claim 1, wherein the plurality of niobium titanium composite oxide particles comprise primary particles which contain niobium titanium composite oxide,
wherein an aspect ratio of the primary particles is in a range of 1 or more to less than 4, and
wherein the aspect ratio is represented by L/S where L is an arithmetic mean value of lengths of major axes of the primary particles and S is an arithmetic mean value of lengths of minor axes of the primary particles, each of the minor axes being direction of the niobium titanium composite oxide, each of the major axes being direction of the niobium titanium composite oxide and/or direction of the niobium titanium composite oxide.
