This electrode for a power storage device is provided with carbon nanotubes, graphene, an ionic liquid, and a three-dimensional mesh-like metal porous body that holds the carbon nanotubes, graphene and ionic liquid in pores. The percentage of the total amount of carbon nanotubes and graphene relative to the amount of ionic liquid is 10 mass% to 90 mass%, and the mass ratio between carbon nanotubes and the graphene is within a range of 3:7 to 7:3. L'invention concerne une électrode pour un dispositif de stockage d'énergie qui est dotée de nanotubes de carbone, de graphène, d'un liquide ionique et d'un corps poreux métallique de type maille tridimensionnelle qui maintient les nanotubes de carbone, le graphène et le liquide ionique dans les pores. Le pourcentage de la quantité totale des nanotubes de carbone et du graphène par rapport à la quantité du liquide ionique est 10 % en masse à 90 % en masse, et le rapport en masse entre les nanotubes de carbone et le graphène se situe dans une plage de 3:7 à 7:3.
