An inventive partitioned closed container comprises a cylindrical main body, a partition provided within said main body in a body therewith along the longitudinal direction thereof and lids for closing openings of the main body. The lids are joined with the main body and the partition by means of frictional agitating joining or laser welding. Thereby, it is possible to realize a good joining condition and to assure reliability in terms of strength without increasing the weight and the cost.
