Beschreibung
Zusammenfassung:	Provided is a binder composition that exhibits sufficient adhesion and that achieves the excellent dispersibility of a conductive auxiliary agent. The binder composition according to an embodiment of the present invention is a binder composition containing a vinylidene fluoride copolymer composition containing vinylidene fluoride and an acrylic monomer; the acrylic monomer being at least one type selected from acrylic acid and methacrylic acid; and a ratio (Mn2/Mn1) of a number average molecular weight of the vinylidene fluoride copolymer composition after being adsorbed onto alumina (Mn2) to a number average molecular weight of the vinylidene fluoride copolymer composition before being adsorbed onto alumina (Mn1) being less than 2.
