PROBLEM TO BE SOLVED: To provide a polarizable electrode that prolongs the life of an electric double layer capacitor, and to provide the electric double layer capacitor using the same. SOLUTION: The metal oxide particle-containing polarizable electrode is formed by bringing a carbon material porous body containing a carbon material and a binder polymer, into contact with low-valency transition metal oxide particles of 1 to 40 nm in mean particle diameter, for example, trimanganese tetraoxide, the metal oxide particles being carried by the carbon material porous body.
