In a conventional electrochemical cell, since a welding between a container and a sealing plate is performed in the atmospheric air, a weld zone is oxidized and a corrosion resistance decreases. For this reason, impurities are eluted from the weld zone into an electrolyte, and this causes an internal resistance increase and a capacity decrease of the electrochemical cell. Further, there is a possibility that an organic solvent in the electrolyte is oxidized by the welding. According to the invention, in order to solve the above problems, the seal welding between the container and the sealing plate of the electrochemical cell is performed under an inert atmosphere.
