| 1. An electrochemical device, comprising:
an integrated body produced by alternately disposing a plurality of collectors each having polarizable electrode layers formed
on surfaces thereof and a plurality of separators for separating the adjacent polarizable electrode layers;
a pair of integration fixing plates disposed on both sides of the integrated body in a lamination direction; and
a plurality of fixing pins that pass through the integrated body and the integration fixing plates, wherein
the separators and the collectors have first and second through-holes respectively, into which the fixing pins are inserted,
with the diameter of the second through-holes being larger than that of the first through-holes.
