The active material layer contains particles of a monoclinic β-type titanium complex oxide and particles of a lithium titanate having a spinel structure. When a particle size frequency distribution of particles contained in the active material layer is measured by the laser diffraction and scattering method, a first peak P1 appears in a range of 0.3 μm to 3 μm and a second peak P2 appears in a range of 5 μm to 20 μm in the frequency distribution diagram. The ratio FP1/FP2 of the frequency FP1 of the first peak P1 to the frequency FP2 of the second peak P2 is 0.4 to 2.3.
