1. a manufacture method for electrode assemblie, comprising:

  • Step (S11), forms the caught portion caved in the inside from the edge of the first electrode and the second electrode;

    Step (S20), form unit structure body, described unit structure body has 4 Rotating fields that described first electrode, the first barrier film, described second electrode and the second barrier film are stacked gradually or the structure that described 4 Rotating fields are laminated repeatedly, or will described first electrode, described first barrier film, described second electrode and described second barrier film alternately be configured and the two or more basic monomer be combined as a whole by the order of specifying each each stacked 1 and the structure that there are described 4 Rotating fields or make described 4 Rotating fields repeatedly configure;

    Step (S31), the region corresponding with described caught portion of stay limit to intercept described first barrier film that described unit structure body has and described second barrier film, and also form caught portion at described first barrier film and described second barrier film;

    AndStep (S41), forms electrode assemblie to enable the stacked multiple unit structure body of the described caught portion mode in opposite directions of adjacent unit structure body.
