摘要： A welding device (40) welds resin units (20, 30) to an electrode plate (11) serving as a workpiece. The welding device (40) is provided with: a heating unit (54) that heats and melts the resin unit (20, 30); a pressing unit (51) that presses the melted resin units (20, 30) in a pressing direction (Z) toward the electrode pate (11) via a sheet material (60) to weld the melted resin units (20, 30) to the electrode plate (11), the pressing unit (51) having a pressing surface (51b) that presses the sheet material (60); a pair of support units (73a, 73b) arranged to be separated in a movement direction (T) crossing the pressing direction (Z), the pair of support units (73a, 73b) supporting the sheet material (60) so that the sheet material (60) covers the pressing surface (51b) in the pressing direction (Z); and a movement mechanism (70) that slides the sheet material (60) supported by the support units (73a, 73b) in the moving direction T.

摘要： An electrode unit manufacturing device 50 is an electrode unit manufacturing device for manufacturing an electrode unit 11A by welding a resin member 21B to a bipolar electrode 11 including a current collector 15, and an active material layer provided on one surface 15a and the other surface 15b of the current collector 15. The electrode unit manufacturing device includes a robot hand 30 that transports the bipolar electrode 11 in the air while suctioning and holding the bipolar electrode 11, and a welding device 40 including a welding unit 45 that welds the resin member 21B to the bipolar electrode 11 in a state of being suctioned and held in the air by the robot hand 30.
