This binder resin for electricity storage devices is a binder composition for forming an electricity storage device, which contains a polymer (A) and a liquid medium (B). The polymer (A) contains, per 100 parts by mass thereof, 0.5-20 parts by mass of a repeating unit (Ma) that is derived from a fluorine-containing ethylene monomer, 41-60 parts by mass of a repeating unit (Mb) that is derived from an unsaturated carboxylic acid ester, and 16-40 parts by mass of a repeating unit (Mc) that is derived from an aromatic vinyl compound. La présente invention porte sur une résine de liant pour dispositifs de stockage d'électricité qui est une composition de liant pour former un dispositif de stockage d'électricité, et contient un polymère (A) et un milieu liquide (B). Le polymère (A) contient, pour 100 parties en masse de celui-ci, 0,5-20 parties en masse d'une unité récurrente (Ma) qui est issue d'un monomère d'éthylène contenant du fluor, 41-60 parties en masse d'une unité récurrente (Mb) qui est issue d'un ester d'acide carboxylique non saturé, et 16-40 parties en masse d'une unité récurrente (Mc) qui est issue d'un composé de vinyle aromatique.
