Nonaqueous electrolyte battery, electrode for the same, and battery pack

According to one embodiment, there is provided an electrode (10) for a nonaqueous electrolyte battery (1). The electrode (10) includes an active material layer (10b). The active material layer (10b) includes a monoclinic ²-type titanium composite oxide. When the electrode (10) is subjected to an X-ray diffraction measurement using a Cu-Ka ray source, a ratio of a reflection intensity 1(020) of a peak derived from a plane (020) of a crystal of the monoclinic ²-type titanium composite oxide to a reflection intensity 1(001) of a peak derived from a plane (001) of the crystal of the monoclinic ²-type titanium composite oxide being in the range from 0.6 to 1.2.
