An object of the invention is to provide vinylidene fluoride copolymers exhibiting higher adhesion with respect to metal foils than do conventional vinylidene fluoride copolymers, and to provide uses of the vinylidene fluoride copolymers. The vinylidene fluoride copolymers of the invention are obtained by copolymerizing vinylidene fluoride with a compound represented by Formula (A). In Formula (A), R 1 , R 2 and R 3 are each independently a hydrogen atom, a chlorine atom or an alkyl group; and X is an atomic group with a molecular weight of not more than 500 containing a heteroatom and having a main chain composed of 1 to 20 atoms, or is a heteroatom. |
