In a fuel cell (100) including an electrolyte membrane (1) and a pair of electrodes (2, 3) disposed on both sides of the electrolyte membrane, at least one of the electrodes has an electrically conductive nanocolumn (4) that is oriented with an inclination of 60 DEG C or less with respect to a planar direction of the electrolyte membrane, a catalyst (5) supported on the electrically conductive nanocolumn, and an electrolyte resin (6) coating the electrically conductive nanocolumn.
