Abstract: An electrochemical device manufacturing jig comprises a first fixing jig having a plurality of fixing pins, for positioning and fixing separators by inserting the plurality of fixing pins in through-holes provided to the separators, a second fixing jig having a plurality of positioning pins, for positioning and fixing collectors by inserting the plurality of positioning pins in through-holes provided to the collectors, and a fixing pin hold-down jig for supporting fixing pins. The first and second fixing jigs can be mated in a direction parallel to the axial direction of the fixing pins and the positioning pins, and this allows the relative positional relationship of the fixing pins and the positioning pins to be fixed.

Abstract: An electrochemical device of this invention has a stacked member, in which a plurality of collectors having polarizable electrode layers formed on the surfaces thereof and a plurality of separators which separate the adjacent polarizable electrode layers are arranged in alternation, and a pair of fixed collecting plates arranged on both sides in the stacking direction of the stacked member. The pair of fixed collecting plates has a depressed portion which exerts pressure on the stacked member and a protruding portion which forms a gap with the stacked member. The protruding portions terminate at the peripheral portions of the fixed collecting plates so that gaps are formed between the stacked member and the fixed collecting plates. These gaps serve as permeation apertures for electrolytic solution.
