The terminal includes an upper connecting part extending outside the case from a middle connecting part, and a current collector connecting part extending inside the case from the middle connecting part. The sealing member includes an upper sealing part seated on the cap plate and a lower sealing part disposed in and affixed to the terminal hole in a sealing relationship with respect thereto, the upper sealing part being between the cap plate and the upper connecting part to support the upper connecting part in a spaced apart relationship with the cap plate, the lower sealing part being between the current collector connecting part and an entirety of the terminal hole.
