Provided is an electrode (3) including a current collector (3a) and an active material-containing layer (3b) in contact with the current collector (3a). The active material-containing layer (3b) contains a carbon nanotube and particles of titanium-containing oxide having an average particle size or 0.1 µm to 3 µm. A peel strength between the current collector (3a) and the active material-containing layer (3b) is within a range of 0.2 kN/m to 0.7 kN/m.
