An object of the present invention is to provide an all-solid battery having high energy density. The problem can be solved by a negative electrode for an all-solid battery comprising: a carbonaceous material having a true density of from 1.30 g/cm 3 to 1.70 g/cm 3 determined by a butanol method, a specific surface area of from 0.5 to 50.0 m 2 /g, an average particle size D v50 of from 1 to 50 µm, and a combustion peak T (°C) according to differential thermal analysis and a butanol true density Á Bt (g/cm 3 ) satisfying the following formula (1): 300 ‰¤ T ˆ’ 100 × Á Bt ‰¤ 570 and a solid electrolyte.
