することができる。Arranged at specified intervals! Protrusions 6 for positioning the cells 1 are formed at predetermined intervals on the bent belt 5, and are rotationally driven by a driving means (not shown). The lead 2 is
It is supplied wound on a reel 7 arranged above and below the cell 1 which is transported by the belt 5. The lead 2 pulled out from the reel 7 is guided by rollers 8 that are rotatably disposed close to the top and bottom of the cell 1, and is supplied to the cell 1. Note that the reel 7 has a lead 2.
When pulled out, a small braking force or rotational force in the winding direction is applied to prevent it from rotating due to its inertia. Therefore, no slack occurs in the lead 2 supplied to the cell 1. Further, if a shallow groove into which the flexible film 3 is fitted is formed on the circumferential surface of the row 28, it is possible to prevent the leads 2 from falling horizontally.
Support shafts 11 are placed on the plates 10 arranged parallel to each other so as to face the leads 2 sent together with the cells 1.
It is supported slidably in the direction perpendicular to the force/cell 1. A roller 12 is rotatably supported at one end of the support shaft 11 and is urged in a direction to be pressed against the lead 2 by a spring 15 mounted on the support shaft 11 . The irradiation optical system 14, which is provided between the support shafts 110 so as to face the lead 20 passage, is connected to a laser oscillator 16 via an original fiber 15. Therefore, the laser beam 17 oscillated by the laser oscillator 16 can be irradiated onto the lead 2 that follows in front of the irradiation optical system 14 .

的に直列に接続することができる。In the above configuration, the leads 2 pulled out from the reel 7 disposed above and below the channel of the cell 1 and facing each other across the channel of the cell 10 are connected so that the rear end of the nth thin film 4 of one lead 2 is connected to the other. The lead 2 is positioned so as to face the tip of the (n+1)th thin film 4 and pulled out. By connecting a dummy cell (not shown) K placed between the projections 6 of the belt 5 between the leads 20, the lead 2 can be pulled out in synchronization with the movement of the belt 5. In this state, when the cell 1 is placed between the projections 60 of the belt 5 while moving the belt 5 at a constant speed, the cell 1 and the lead 2 are fed synchronously and are fed between the rollers 12. , the lead 2 is pressed against the cell 1 by the force of the spring 15, and the cell 1 and the thin film 4 of the lead 2 are closely layered. In this state, when the laser beam 17 is irradiated onto the lead 2 from the irradiation optical system 14,
The thin M4 in the part that received the laser beam 17 melts and the cell 1
is joined to. When the cell 1 passes between the rollers 12, the rollers 12 are pushed by the force of the spring 13, pressing the thin films 4 of the opposing leads 2 into close contact with each other. In this state, when the laser beam 17 is irradiated, the thin M4 of the lead 2 is melted and joined. In this way, the thin film 4 of the lead 2 connected to the light-receiving surface side of the nth cell 1 and the thin film 4 of the lead 2 connected to the non-light-receiving surface side of the (n+1)th cell 1 are connected. . Therefore, the cells 1 can be electrically connected in series. As above, cell 1 and lead 2
