Zusammenfassung:	PROBLEM TO BE SOLVED: To perform molding work easily in a process of press and the like and improve productivity of a battery and improve a battery life without causing any cracking and peeling off in an electrode mix layer. SOLUTION: In a lithium ion secondary battery formed of a positive electrode which has active material for storing and releasing the lithium ion and a negative electrode which has active material for storing and releasing he lithium ion, a polymer of chlorotrifluoroethylene and vinylidene fluoride in which content of chlorotrifluoroethylene is 8-20wt.% is used as binding agent used for the positive electrode and/or the negative electrode.
