Claims (1)

[Scope of Claim for Utility Model Registration] (1) The patterned conductor is formed on an insulating sheet thinner than the thickness thereof, and at least three or more of the insulating sheets are laminated to form a laminate, and the area near the edge of each of the above insulating sheets is reaching the edge of the pattern conductor, connecting pieces having the same thickness as the patterned conductor are successively formed facing each other through insulating sheets, and the conductor layer is continuous over all the connecting pieces and the edges of all the insulating sheets. Only in some of the insulating sheets on which the patterned conductors to be connected to each other among the plurality of insulating sheets are formed, the patterned conductors and connection pieces are connected to each other, and the patterned conductors on different insulating sheets are connected to each other. A laminated wiring body in which required connections are made through the conductor layer. (2) The laminated layer according to claim 1 of the utility model registration claim, wherein the stacked portion of the connecting pieces has a concave portion formed along the stacking direction at the peripheral edge thereof, and the conductive layer is embedded in the concave portion. wiring body.
