A part where separator layers 48 of resin are laminated on each other with heat-resistant layers 49 interposed among them and a sheath (laminated sheet) 13 is laid on each side of the laminated separator layers is held, pressurized, and vibrated by a pressure vibrator 111 and a jig receiver 112. The pressure vibrator 111 and jig receiver 112 are provided with projections 121 that pressurize, vibrate, and break the heat-resistant layers 49, thereby melting and welding together the resin of the separator layers 48 at the broken part 200. |
