1. folded-sheet honeycomb structure body, formed by a plurality of unit that are arranged in rows, comprise such unit:

  • described unit has two half-cells that form 3D structure (1 and

         2), described half-cell vertically abuts to form the side cell-wall each other, the described side cell-wall formation annular cross section that is adjacent to each other, each unit at the first opening surface and the second opening surface take cover layer face as the boundary, thereby so that each cell mesh ground or bridge joint in one of cover layer face fully;

    Described 3D structure (1 and

         2) is formed by the deformation of substantially uncut flat body thermoplastic, simultaneously thermoplastic deformation forms join domain (3 and

         4), described 3D structure is folded into described unit mutually with facing, described unit at one end has by join domain (3,4) confining surface that forms, join domain (3,4) is arranged in one of cover layer face of folded-sheet honeycomb structure body.
