Abstract:
Provided is a carbon material that is large in specific surface area, and moreover, capable of easily forming an electrode film even when any binder is substantially not contained. Provided is a carbon material that has a BET specific surface area of 100 m2/g or more, with the weight of the carbon material remaining on a sieve after shaking being 90% by weight or more with respect to 100% by weight of the carbon material put in the sieve, when 0.2 g of the carbon material packed in a cylindrical syringe of 2 cm in diameter is compressed at a pressure of 16 kN, the whole of the compressed carbon material is taken out from the syringe and put in the sieve with an aperture of 4.75 mm, and the sieve is shaken for 1 minute.
