Protrusions 6 for positioning the cells 1 are formed at predetermined intervals on the belt 5 arranged at predetermined intervals, and are rotationally driven by a driving means (not shown). The lead 2 is connected to the cell 1 transported by the belt 5.
It is supplied wound on a reel 7 arranged vertically. 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 a small braking force or a rotational force in the winding direction is applied to the reel 7 so that the reel 7 does not rotate due to its inertia when the reel 2 is pulled out. Therefore, no slack occurs in the lead 2 supplied to the cell 1. Further, by forming a shallow groove in the circumferential surface of the roller 8 into which the flexible film 3 fits, it is possible to prevent the lead 2 from shifting laterally. Support shafts 11 are provided on the plates 10 arranged above and below the cell 1 and parallel to the cell 1 so as to face the leads 2 sent together with the cell 1.

The rear end of the thin film 4 (n
It is positioned so as to face the tip of the +1)th thin film 4 and pulled out. In this state, when the cell 1 is placed between the projections 6 of the belt 5 while moving the belt 5 at a constant speed, the cell 1 and the lead 2 are fed synchronously and sent between the rollers 12. Then,
The lead 2 is pressed against the cell 1 by the force of the spring 13,
The thin films of cell 1 and lead 2 are in close contact with each other. In this state, the laser beam 17 is emitted from the irradiation optical system 14 to the lead 2.
When the thin film 4 is irradiated with the laser beam 17, the portion of the thin film 4 that receives the laser beam 17 is melted and bonded to the cell 1. roller 1
When cell 1 passes between 2, roller 12
Pushed by the force of the spring 13, the thin films 4 of the opposing leads 2 are pressed against each other and brought into close contact with each other. In this state, when the laser beam 17 is irradiated, the thin film 4 of the lead 2 is melted and bonded. 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,
