An object of the present invention is to provide a binder composition for a solid electrolyte battery and a slurry composition for a solid electrolyte battery that is excellent in processability and capable of exhibiting excellent battery characteristics in a solid electrolyte battery. The binder composition of this invention contains the particulate-form polymer of the copolymer containing an acrylate-type monomer unit and an aromatic-type monomer unit, the alkyl-modified cellulose represented by Formula (I), and an organic solvent. On the other hand, in formula (I), R 1 , R 2 and R 3 each represent a hydrogen atom or an alkyl group having 1 or more and 4 or less, and R 1 , R 2 in 50 mol% or more of the total repeating units. and at least two of R 3 are alkyl groups having 2 or more and 4 or less carbon atoms. In addition, n represents a natural number. |
