         6 . The sealing material according to  claim 1 , wherein the glass ribbon has a surface subjected to film forming treatment. 
     
     
         7 . A lighting device, comprising a member using the sealing material according to  claim 1 . 
     
     
         8 . A solar cell device, comprising a member using the sealing material according to  claim 1 . 
     
     
         9 . A display device, comprising a member using the sealing material according to  claim 1 . 
     
     
         10 . A sealing method, comprising the steps of arranging a sealing material which is formed of a glass ribbon having a thickness of 1 to 100 μm an at a predetermined location of an adherend, and heating the sealing material to adhere the adherend and the sealing material to each other. 
     
     
         11 . The sealing method according to  claim 10 , wherein the adherend and the sealing material are adhered to each other by heating contact surfaces of the adherend and the sealing material. 
     
     
         12 . The sealing method according to  claim 10 , wherein the adherend and the sealing material are adhered to each other by heating a part of the contact surfaces of the adherend and the sealing material. 
     
     
         13 . The sealing method according to  claim 10 , wherein the adherend is a glass substrate. 
     
     
         14 . The sealing method according to  claim 13 , wherein the glass substrate has a thickness of 10 to 200 μm.
