Abstract
Provided is a binder composition for an all-solid-state battery with which an all-solid-state battery having excellent capacity characteristics can be obtained. The binder composition contains: a copolymer including an alkylene structural unit and a nitrile group-containing monomer unit; and an organic solvent having a boiling point of 100° C. or higher. The copolymer includes the nitrile group-containing monomer unit with a percentage content of at least 10 mass % and not more than 30 mass % and has an iodine value of at least 40 mg/100 mg and not more than 130 mg/100 mg.
