1. An electrode comprising:
a current collector; and
an active material-containing layer which is formed on a surface of the current collector and comprises a plurality of niobium titanium composite oxide particles,
wherein a X-ray diffraction pattern using a Cu-Kα ray source with respect to a surface of the active material-containing layer comprises a peak A with a highest intensity in a range of 2θ=26°±0.2° and a peak B with a highest intensity in a range of 2θ=23.9°±0.2°,
wherein an intensity ratio (Ia/Ib) between an intensity Ia of the peak A and an intensity Ib of the peak B is in a range of 1.80 or more to 2.60 or less, and
wherein the plurality of the niobium titanium composite oxide particles have a major axis oriented towards an in-plane direction of the current collector.
