Abstract: Provided is a binder composition for a non-aqueous secondary battery positive electrode that can form a positive electrode with which it is possible to obtain a non-aqueous secondary battery having excellent life characteristics even when aging treatment is carried out under low-temperature and low-depth of charge conditions. The binder composition contains a first binder, iron, and at least one of ruthenium and rhodium. The total iron, ruthenium, and rhodium content is no greater than 5×10−3 parts by mass per 100 parts by mass of the first binder.
