Abstract: A continuous electric/electronic device and a method of manufacturing the same are disclosed. The method of manufacturing a continuous electric/electronic device having a serial connection structure comprises (a) disposing a first electrode current collection unit, (b) disposing first organic•inorganic material in regard to the first electrode current collection unit, (c) laminating a first area of a second electrode current collection unit on the disposed first organic•inorganic material, (d) disposing second organic•inorganic material in regard to a second area of the second electrode current collection unit and (e) laminating a third electrode current collection unit on the disposed second organic•inorganic material. Here, the first area and the second area of the second electrode current collection unit operate as current collection units having different polarity in regard to adjoining first organic•inorganic material and second organic•inorganic material.
