According to the present invention, an organic electroluminescence device is manufactured using a roll-to-roll process. The manufacturing method includes an element forming step of forming a plurality of organic EL elements (3) on the band-shaped flexible substrate (2), a step of forming a sealing film (3) on the plurality of organic EL elements (3) by interposing a thermosetting or photo- 5), and a winding step of winding the strip-shaped laminate 10 having the strip-shaped flexible substrate 2, the organic EL element 3 and the sealing film 5 into a roll shape. The uncured adhesive layer is formed on the back surface of the sealing film 5 except for both ends of the back surface of the sealing film 5, and after the winding step, the laminated body 10 is heated or irradiated with light Thereby curing the adhesive layer. |
