According to one embodiment, an electrode (4) is provided. The electrode (4) includes an active material containing-layer (4b). The active material containing-layer (4b) includes active material particles containing at least one selected from a niobium titanium composite oxide and a composite oxide which is expressed by the general formula Li x M1 1-y M2 y Ti 6-z M3 z O 14+´ . The active material particles include primary particles having an average particle diameter of 0.1 to 10 µm and secondary particles having an average particle diameter of 1 to 30 µm. A pore diameter distribution of the active material containing-layer which is obtained by mercury porosimetry has a first peak which has a maximum value within a range of 0.01 to 2 µm and a second peak which has a maximum value within a range of exceeding 6 µm and equal to or smaller than 20 µm. An intensity of the second peak is 1/10 to 1/5 of an intensity of the first peak.
