Claim 0:
1. A binder composition for an all-solid-state secondary battery comprising a polymer A, wherein
the polymer A includes a nitrile group-containing monomer unit and an aliphatic conjugated diene monomer unit, with proportional content of the nitrile group-containing monomer unit in the polymer A being not less than 5 mass % and not more than 30 mass %, and proportional content of the aliphatic conjugated diene monomer unit in the polymer A being not less than 40 mass % and not more than 95 mass %,
the polymer A has an iodine value of 250 mg/100 mg or more, and
the polymer A has a Mooney viscosity (ML1+4, 100° C.) of 65 or more.
