Provided is a composition for forming an undercoat layer of an energy storage device, the composition comprising carbon nanotubes, a carbon nanotube dispersant, and a solvent, the total content of metal impurities in the carbon nanotubes being less than 5 mass%, and the respective contents of cobalt and manganese in the carbon nanotubes both being less than 0.01 mass%. This composition makes it possible to provide an undercoat layer that exhibits the effects of reducing resistance and suppressing an increase in resistance. |
