ABSTRACT:
An electrochemical cell has a container housing a separator and a pair of electrodes impregnated with an electrolyte. The container has a base member having a bottom part and a side part disposed on a top surface of the bottom part along an outer rim of the bottom part. A metallic conductive terminal has first and second opposite surfaces penetrating through inner and outer sides of the base member. The first surface of the conductive terminal is disposed on the top surface of the bottom part of the base member. The second surface of the conductive terminal is disposed in contact with one of the pair of the electrodes. A metallic frame member has first and second opposite surfaces, with the first surface being joined to an entire rim of a top surface of the side part of the base member. A metallic cover member is joined to an entire rim of the second surface of the frame member.
