Abstract

PURPOSE:To reduce connection space by interposing an elastic member at a part corresponding to through-hole between each printed-wiring board and by connecting printed-circuit boards with a conductive rivet while the elastic member is contracted for allowing the connection part to be conducted. CONSTITUTION:A compression spring 3 is interposed between flexible printed- wiring boards 1 and 2 and a head 4b and a tip 4c of the rivet 4 are pressed while a conductive rivet 4 is penetrated for the compression spring 3 and through-holes 14 and 24. At the same time, the outer diameter of an axial part 4a is expanded and is adhered to connection parts 13 and 23 and the compression spring is contracted elastically. It reduces connection space as well as connection cost and contact resistance.
