Provided are a binder composition for a solid electrolyte battery and a slurry composition for a solid electrolyte battery that have excellent processability and can cause a solid electrolyte battery to display excellent battery characteristics. The binder composition contains a particulate polymer of a copolymer including an acrylate monomer unit and an aromatic monomer unit, alkyl-modified cellulose represented by formula (I), and an organic solvent. In formula (I), R 1 , R 2 , and R 3 each indicate a hydrogen atom or an alkyl group having a carbon number of at least 1 and not more than 4. At least two of R 1 , R 2 , and R 3 are alkyl groups having a carbon number of at least 2 and not more than 4 in 50 mol % or more of all repeating units. Also, n indicates a natural number. |
