The active material containing-layer 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 LixM11-yM2yTi6-zM3zO14+δ. 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 ⅕ of an intensity of the first peak.
