PROBLEM TO BE SOLVED: To reduce useless space in a case.SOLUTION: A support member 33 is drawn near to a first sidewall 22a side by screwing the male screw 321a of an internal connection part 32a and the female screw 33c of the support member 33. A collector 31 is held between a first counter surface 321b of a flange 32b and a second counter surface 331a of a body 33a. Consequently, electrification path of an electrode assembly 11, a tub 12c, the collector 31, the support member 33, and an electrode terminal 32 is formed, without welding the collector 31 and the electrode terminal 32. |
