PROBLEM TO BE SOLVED : To improve battery characteristics such as reversible capacitance and initial charge/discharge efficiency with excellent repeatability in a lithium ion secondary battery with an electrode using a carbonaceous material put under surface treatment by thermal plasma or the like. SOLUTION : In manufacturing the electrode with the carbonaceous material put under the surface treatment bonded with a binder, a process of transferring the carbonaceous material into rare gas without exposing it in air and bonding it with the binder in the rare gas is provided after the surface treatment.
